Contact Patch: Motorcycle Tire Warmers

[@louscannon6265]

This knowledge and confidence layed down in the most practical and informative way. This is the best thing I have discovered without an inch of attitude, Dave Moss is giving you everything. Absolute Gold.

[@catalystreactionsbw]

Thank you I must!

[@AuMechanic]

Wish we had tyre warmers in the 80s when I raced. Back then it was like motocross the first 2 laps before the slicks got to temp which on a 1000cc super bike was pretty hairy. Lost the front a few times from it trying to break away from the pack, one time a very costly write off.

[@catalystreactionsbw]

That's when we would cut the back of the sipe off with a hot tyre knife knowing it would soon be a level side verses a bunch of steps.

[@Botpoint21]

Happened to me. Had a borrowed generator that wasn't outputting proper power. Thought my tires were hot, until I feel in turn 3. Great info sir.

[@catalystreactionsbw]

Thank you! Glad you check temperatures!

[@Vizr]

Matt, I watched your vids when you rode the ridge. I also fell victim to T3 when my rear tire went cold.

[@powerbreed]

I’m glad you included Celsius temperatures 😅

[@RyGriff]

Thank you Dave. I just bought Woodcraft Warmers for track days and this was super helpful.

[@catalystreactionsbw]

Great to hear!

[@mr.quiroga2284]

Great info Dave... i always wondered if you needed warmers on a hot day, summed it up in one video

[@stefanocappelletti7529]

we are most popular tyrewarmers in the world and i would show how we work since 1996. Thank you

[@Szlejer]

Extremely helpful and informative content even for a racetrack newb like me. Thanks!

[@sylvandespres7654]

absolutely. there's no reasons these days to experiment with the success-fail process.all the info is there to gets you on track in the most safe manner possible.

[@verdeboyo]

Dave you are a world of knowledge. I'm in the process of buying a set and your info is so helpful.👍🏻👍🏻👍🏻

[@catalystreactionsbw]

Glad the content was helpful. Thanks for watching :)

[@Stan_in_Shelton_WA]

The wheel and tire will transfer heat to your hand at different rates. Stick your hand in 180 degree water, ouch! but a tire, okay.

[@jackass7221]

Just a thought. If that ramp you have is made of aluminium, then that will act as a heat sink and may actually by drawing heat away from the tire on the bottom.

[@Konstantinos340]

heat is such a simple and complex topic at the same time.

[@Nasrou89]

Thanks for the free video

[@funninja1405]

FANTASTIC MATERIAL !

[@cachidril]

great video. very ilustrative

[@dariodipaola8445]

Damn I can smell those tires cooking... oh shit that's my computer xD

[@garymanning8920]

For a street tire...Dunlop Q3 Sportmax...on my CBR, if I only use careful lapping to warm up...on a 90 degree day which, is normal all summer, I do not have tyre warmers yet. CAN I get to safe temps after 10 minutes riding? Or is this a, too many variable, question? I am purchasing a tire temp gauge as we speak. I also get about 20 minutes warm up to the canyon I ride through... quite spirited riding never a slip at safe high speed cornering 1 hour ride in the canyon. Checked the tyre by hand and I could hold my hand indefinitly... 120f is my guess. More friction on track so they must get hotter on track then canyon rides.?? Probably a bad question on

[@catalystreactionsbw]

You can get to optimal temperatures in less than 10 minutes of riding. With the bike at 90 degrees to the sun so both wheel get hot, you could be at temperature within 2 laps. See if you can acquire tyre warmers that are broken as they will most certainly help keeping the heat in the tyre and ensuring UV has minimal impact.

[@kaargh6924]

I emailed Dunlop and asked about warmers for the q3+'s. They told me there is no benefit to using warmers on those at all as they are designed to heat up quite quickly on the road

[@catalystreactionsbw]

@@kaargh6924 Yes, that is their comment. In the end it comes down to us and how we master our emotions/brain. If warmers are used to make us "feel" better they should be on low. The beauty is we can choose what we want given the information we gather.

[@sylvandespres7654]

i see you recommended a certain brand of tire warmer...what are they? i remember there was NO tire warmers in the 80's back when i was active on the national championnship....was racing an RG500 gamma bored to 680.....god warmers would have been of some ......interest to say the least LOLOL!!!!....the positive aspect of it is ,we were used to feel the high side coming lol

[@catalystreactionsbw]

I too raced with no tire warmers in the mid 90's and one of the critical learning curves for me was how fast to go on the first lap with cold tires. I'm very grateful for that lesson as it gave me the knowledge and skills to leverage when the warmers failed. The warmers I have had the best longevity with are Moto-D and they also have a warranty on them.

[@michaelkuhno]

Dave - you mention on hot days turning the warmer to the Warm setting (if available) and then setting to Hot 10-15 mins before the session. Don't most tire warmers have a thermostat and if left on High would keep the tire at the desired/target temperature w/o this added step?

[@catalystreactionsbw]

Most warmers do have a thermostat set at 180F that you can leave at that temp all day, some offer more choices. Tire manufacturers suggest time periods for warmers at those temps after a lot of research and testing, most from 30-50 minutes only. Would you like to be wrapped at 180F for 7 hours?

[@michaelkuhno]

Thanks for the reply Dave. I meant more for people running sessions at a track day if they were to just keep the warmers set to the Hot temp (assuming the org is running three 20 min sessions) then they'd most likely have the warmers on and ready to rock with approx 30 mins on hot (the extra 10 mins due to takeoff of warmers, staging to grid, return to pit area, setup on stands and yes, cleaning tires - good point!) in between sessions. However - it is good to note that leaving the warmers on Hot over lunch time (when the bike might be sitting for 1.5 hours depending on how the day is run) might be a little excessive. I'm in the habit of setting the warmers to Warm when I return to the pits before lunch and then switching them back to Hot before I suit up. Seems to work out OK and I rarely, if ever, forget to switch them back. As always - thanks for all the great info and insight!!

[@catalystreactionsbw]

Mike - on a 4 group format of 15 minutes that is fine. With a 3 group format if the temp is above 95F, then sun on the wheels will maintain the heat in the tires In the end, do what makes you happy and stick with it as when you roll out on the track, you need to focus on skills not be concerned with things you may or may not have done.

[@greybravo1]

In terms of soft and hard carcasses. What would michelin street tires be considered vs perelli being soft and dunlop being harder?

[@catalystreactionsbw]

Unfortunately there is no rule of thumb with street tires so you have to sit on them :) . With race, you would be correct with your sequence and wording.

[@DmanGuitar327]

Hey dave, going from a q3+ to a q4 this season, i ride twisties n 3 track days this year. Should i go with the 180 60? What do i need to change to run a 60 over a 55?

[@catalystreactionsbw]

Ride. If the 60 series turns better for you - nothing needed. If you feel it turns too fast, change the fork position to flatten the bike out.

[@DmanGuitar327]

@@catalystreactionsbw so if its too quick lower raise the fork in the triple tree?

[@catalystreactionsbw]

@@DmanGuitar327 that is correct, 2-3mm if needed.

[@joilsongomes5]

i have the cheap tire warmers what i do is put them on as soon as get in the track no meter what, is that bad i know they turn on and off by themselves.

[@catalystreactionsbw]

You need to know how hot they get and then how long the tires need to be at that heat level prior to setting hot pressures. If you get the timing right, no it is not bad. If you have them on full heat in the middle of summer, that might not be favorable, so them you set an amount of time they are on prior to going on track.

[@THE_ONE_86]

whats a general rule of thumb hot to cold temps dave?

[@catalystreactionsbw]

Cold to hot temps for road tires would be ambient to 50C. For track tires they should come off track at 60-65C in the braking and drive portions of the tyre.

[@THE_ONE_86]

i run a racing side car, we normally run around 111-13 psi cold temps

[@sivonparansun]

Do you have a recommendation on generator for running 1 vs 2 sets of tire warmers. Everyone raves about Honda's but there are so many less expensive & more powerful options

[@catalystreactionsbw]

As long as you know what your warmers draw for current/power, you can use any generator. You may need a 1000 but most use a 2000 so it doesn't stress the generator.

[@sivonparansun]

Dave Moss Tuning so badically don't worry about buying a ryobi one from home depot 😅

[@sivonparansun]

Dave Moss Tuning thanks for your response dave

[@zowill68]

Hi Dave - with Bridgestone Slicks, what is the lowest ambient and track temperature you need to run safely (even while using warmers)?

[@catalystreactionsbw]

I've raced with track temps in the 40F range and been 2psi lower off the warmers to get the right temps in the carcass. You cannot let cold air slow you down BUT you have to see what the track gives you for grip at those low temps.

[@jhedges19]

Can you flip these tires or dot track level street tires in general? I ride 2 tracks that really favor right turns.

[@pearcelutz5693]

Ask your tire vendor. Each tire manufacturer has different recommendations.

[@jaybird1806]

Dave- I noticed in the beginning of the video the front warmer got the tire to above 200F. Is this a matter of concern versus the target of 180F?

[@catalystreactionsbw]

Yes, it is noteworthy so going out on track the rubber is slightly over optimal BUT, tires lose heat quickly if you do not keep them under load so a little diligence on the out lap would bring things back in line and then a temp check after 4 laps will create worthwhile data points on carcass temps.

[@Bruce.Wallace]

Dear Lord, that guy with the R1, tell him not to worry about his front tyre temp, he desperately needs a new helmet. That's the worst fitting helmet I have ever seen !!

[@pearcelutz5693]

Holy crap you're right LOL!!!

[@chipper442]

But.....it matches lol.

[@5AXISDLOCKHART]

Do you have a recommendation for a affordable pyrometer to check tire temps?

[@catalystreactionsbw]

Solo racer sells the Longacre pyrometer. soloracer.com/pyrometer.html

[@sylvandespres7654]

@@catalystreactionsbw thanks for the cue Dave.got one on order right after reading your recommendation

[@marcusgeorge1825]

Another hour so 30 minutes later....?

[@mattluettgen]

Do you check temperatures/pressures post-ride?

[@catalystreactionsbw]

You can but you need to do it immediately or before the pace changes to slower speeds as you will lose heat.

[@SK-ps1mo]

So basically buy a good pair of tyre warmers. Are cheaper ones ok looking on eBay hmm

[@catalystreactionsbw]

Here are products that have done their job 100% after three years of use with me (ie 100 plus track days a year). Moto-D, Chicken Hawk, Woodcraft. Capit have just been received but I have no long term data on them.

[@totensiebush]

Do you have a recommendation for warmers that'll fit supermoto/SV650 tires? 160 rear or thereabouts.

[@catalystreactionsbw]

Most manufacturers have warmers for 160 and 200 sizes. Check Chicken Hawk, Woodcraft and MotoD

คนไทยน่าจะมีแบบนี้สักคน..,?
