I want to run 275-45 on a 18x10.5 would it be too meaty i have a 350z doing 700hp so i need meaty tires

[@ChirsSmedely]

@@that350zdude6 the offset is definitely needed to know if they'll fit well. I have 265/35R18s on 18x9.5+40 on my BRZ and the tires fit very square, so a 275 on a 10.5 would probably be closer to a small stretch, but different tire manufacturers fit differently for a given nominal size. I know the Nismo 370Z has 285 width tires on the back from factory, so taking an uneducated guess yours should fit

[@paulythedropbear.3969]

I have 215/45 tyres on 18" by 8" wheels, and they are almost a perfect fit. 225 would better though, the Goldilock zone for that wheel size. Buy wheels to suit the tyre size you want instead of just making them fit. Unless you are more interested in looks vs performance. If you prefer the former, then don't complain when you crash.

[@sti454]

My rule of thumb for stretching tires is to try not go with more than a 1/2" difference between the wheel width and tire width.

[@XFOX1996]

​@@tmoore4356 225/30 is the smallest you can get, or 215/40 but then the sidewall gets bigger. There are no 20" tiers small enough to streach on a 8" rim unfortinetely.

[@3pedalpodcast]

there wouldn't be an issue with that!

[@TheLenki4]

That would be a meat stretch stage 1 i believe since it's a 10" wide wheel. You went one down in width and two up in aspect ration so one minus and two pluses

No such thing as "stages" they just make their own rulebook.

[@flinch622]

@@ssholeEater No sir, you're wrong: my wife did not come with a disclaimer. All spouses arrive in "as is" condition, and your mileage will definitely vary. As for the "stretched" tire thing... it's bad practice [and I hate it], but not as dangerous to roadworthiness as putting in wheel spacers along side lowering springs - suspension parts start begging to break when people do that. I can't think of one reason to have wide rims in search of less contact patch by using an undersize tire - just buy smaller rims.

[@KingJT80]

If youre using wheel spacer you should be using longer studs

[@Krith220]

no

Shorter tire height , better acceleration, speedometer will read fast. Taller tire height,more top speed, speedometer will read slow. Altering your tire height has the same effect as swapping the ring and pinion in the differential, and is cheaper.

[@mattparker3953]

I apologize if this question sounds crazy I'm still learning. I understand you can stretch the width of a tire but can you stretch the diameter? My tire specs are 225/45/17. Can I stretch that on to an 18x8.5 wheel? If not, can I stretch it on to a 18x8 wheel? My tires are designed for 17x7 wheels but I really want an 18 inch wheel with a wider tire but nothing past 8.5. If anybody can help me with this I would appreciate it a lot. I'll even send a dollar to you on PayPal😂

[@lucagrundmann9469]

Matt Parker not sure if i‘m using the right terminology. Not a native speaker. You can’t put a 17 inch tire on an 18 inch wheel because the bead that keeps the tire on the wheel is partly made of steel. And steel won’t stretch. So if you want to run an 18 inch wheel you will need new tires. In this case 225/40R18 (wich a run aswell). My wheels have a 7,5 inch width wich is basically this square look. If I understood Alex right you could go up to 9 inch on this tire (for a stage 3 stretch) before you get problems with debeading
