whats the biggest tire i can put on the stock 16 inch rims? i currently have 245/50/16

 

Putting wider tires on a stock rim is only going to hurt performance. Perhaps it will help in terms of drag strip type performance, but certainly not for anything in the real world or involving turns. It will definately harm handling, (too much sidewall flex due to the extra "bulge"), and more tire means more unsprung weight. Beyond the ideal tire width for a given rim, (which you are certainly at the upper limit of now,) there is little to be gained. If you want to go wider, it's time to step up to bigger wheels. We are fortunate to have a ton of wheelwell clearance. Just try to keep the overall diameter the same as stock.

 

Those 245's are the stock size tires on a 4th gen LT1 Z28.

 

Depends on the rim width,you didn't state what year model car.

 

Sounds like you're probably running the stock salad shooter with an 8" width. If that is the case I probably wouldn't go above a 255. That said, the extra 10mm isn't going to buy you any performance and they're going to cost more. Seems like a lose lose to me, unless you just want the look of a wider tire.

 

would 255 fit though?

 

Hello hello,is there anyone in there lol,you still haven't stated anything about the car except that you have "stock 16s" with 245/50/16 tires.
Assuming it's a 4th gen Camaro with stock 8" wide mags 255s will fit on the rear no problem.

 

ive personally put a 275 on an 8 inch wheel. little sidewall stickin out but thats the look i was goin for. Musicman is running a 315 on what wheel im not sure.

 

255/50/16 tire is the max forthe stock 16x8 wheels.....anything else and you are pushing it if you care.

 

i have a 2000 z28 stock rims, 255 max...okay
