Best Track Wheel Sizing for MR2 Spyder

[@anthonye3680]

Best video ever.. no blog bullshit no dumb crap.. just real car talk and straight to the point...

[@motoringmatt]

Bigger tyres and larger wheels also mean more rotational weight. Extra rotational weight slows down the acceleration significantly, especially for engines with not a lot of torque. It is so much more than just "some extra pounds (or kilos) in the car". Besides, semi-slick tyres are usually extremely heavy. There are some models that contain a lot of metal in their tread and technology. So usually, the tyre gets even heavier than the rim. And the further the extra mass is from the axis of wheel, the more significantly it affects the performance. Good vid tho!

Thats right,in spain we ride on the Mrk24 255/235 17” and on Mr2zz 235/215 17” or some 235 square,what you lose in punch,gain in grip and a much more docile behavior

[@feral4mr2]

Got some 15x8 +32 buddyclubs on mine. 225 45 on front, 245 40 rear. Feels great.

[@ivan_b28]

Did you try 205/225? Would probably be equally fast, a 245 tire doesn’t perform as good on a 8’ rim.

[@feral4mr2]

@@ivan_b28 no, only had those sizes. My track aw11 runs the same tyres and sizes but 8" up front with the 225 and a 9" up rear with the 245. Ar1's seem to have a narrow shoulder, fit the 8" rim without bellow, on the 9" extremely flush with the rim lip.

[@ivan_b28]

@@feral4mr2 oh then that’s fine, a 245 on a 9’ isn’t optimal for max performance but works good. Thought you had the 245 on an 8’, since you didn’t mention the 9’s

[@feral4mr2]

@@ivan_b28 I did have 245 on 8" on the rear of the Spyder. The 245 on 9" is on my aw11 track car.

[@jmartos94]

I found the 17" 215/235 combo maybe a bit too much for a stock 2zz, handling obviously makes a big difference compared to 15" 205 square, but the lack of mid range and the extra 5~6% longer ratio is also pretty much noticeable. A remap easily helps with 10-15hp on that range so maybe it can help to overcome that. For a stock 2zz I think the 15" 205/225 combo would work really nice for street/track use, but tyre choices in 225 are very limited in 15" in (s)pain

[@2zz98]

It depends on wheel cross section tough. I run 17 205 40 which is pretty close to stock ratio.

[@hamsterbrigade]

For everyone following those springs rates just know the tracks are very smooth in California. I'd adjust accordingly based on your track surface.

[@TougeTime]

I am not in California. Haha. My street car is 7k 10k no issue.

[@R1Looter]

I just have 7J tyres, but what would be a better choice of tyre? 205 or 225? First instinct is 225 because it has more contact to the ground.

[@PawelZebra]

In Your older video with TechnoPro Spirit visit, shop owner said that they run 15" 205 front and 16" 225 rear for street use and 16" 225 front and 17" 245/255 for track. Have You ever tried this setup? My 04' MR2 came standard with 15" 185 front and 16" 215 rear and iIm currently searching for new tires for next season.

[@LFOFINAL]

You can run literally any set up on track and street lmao it doesn’t really matter as long as you‘re comfortable with it

[@Catbert814]

I feel like they did that because tire size was quite limited back in the days for 15's. These days you wont have to stagger the diameter to run a wider tire in the rear

[@JudeDacula]

Hey man, I have a 1989 MR2 with 420k miles, does 205 square fit in your car? If it does, do you think it'll fit in my car? Thank you in advance Mr Tougetime

[@zerohikari2685]

I can answer this question. Yes. The AW11 can run 205 squared no problem and 225 squared no problem on 15s.

[@TougeTime]

No. Sell the car.

[@feral4mr2]

I have a couple aw11's and a spyder. 205 square with ease, though run a offset like +25 if you like a flush look. You can also run similar size tyres to what's mentioned in the video. Both my spyder and one of my aw11's share the same set of wheels, 15x8 +32 with 225 45 up front and 245 40 up rear. Granted these are nankang ar1's that seem to have a narrow shoulder for the size. My track aw11 runs 15x8 +25 225 45 up front and 15x9 +35 245 40 up rear. Same tyres as other set of rims.

[@feral4mr2]

@@TougeTime as much as I enjoy my spyder. Aw11 ftw! 🤣

[@zerohikari2685]

@@feral4mr2 Yo, I've been looking to get ahold of you since you are the only other serious AW11 guy I've seen. I"m upgrading to my wheel and tire set up this year for my TT class and wanted to know if 15x9 +35 with 245/40/15s will work in the rear without serious modifications.

[@tobyharcos66]

Hi Emilio, just curious what height of your tires is on the 15’s? I am trying to reverse engineer the height to see if I can get a 16x7.5 +38 with a 225/45r16 up front.

[@minpinracing8462]

Love your content , big fan and subscriber. You said your friend (Gabe) from Japan runs 15X9+30, I can’t seem to find any such size. Can you please confirm his wheel specs? Rims, tires and suspension setup ?

[@twrcrew8852]

prev owner of my car swore only 205 would fit on kosei 15x7 in some hyper-common offset for mr-s (sorry don't remember. but it's "the one" everyone gets). this is on an 01 with Fortune Autos. Now it almost seems pretty far fetched. You sure you don't also have anything else you may have forgotten about? (arms? extensions - such as spacers - etc) I just can't love a bicycle tire on a mid engine sports car. If i could run 245s I'd be so much more visually satisfied and in the future I may be doing the monocrat kit should I be lucky enough to purchase it by the time I can afford one. really hate the look of a 7"

[@jakeartis955]

At a complete loss to know what to put on my 01 car. I was thinking of doing a staggered set up like the face lift cars (15" X 7" EB38 front) + (16" X 7 EB38 rear). Then the question of tyres was something like 195s + width?? (Front) and 205 + widths (rears). I only really use the car on the road but intend to put more power in the future

[@jonwebb9261]

Awesome info! Crazy that 245s fit

[@TougeTime]

Ya pretty much you can fit 255 17 rear with 245f if u needed it. U can fit 275 rear but there aren't many tire options

[@briskmlg]

Heads up to anyone watching, if you run 15x9 +35 using BC DS coils you'll have to remove some material from the lip of where the body mounts to the knuckle. If you haven't gotten coilovers yet, do yourself a favor and get a real set like how Emilio has...

[@TougeTime]

Interesting. I know annex can run 15x9 as well.

Not a big deal. Just did that today on my bc racing rm to fit a 15x9 et35 wheel.
