I've read through the threads but I haven't found what I'm looking for.

I have the stock staggered 18/19" wheels and I'm happy to stay with those. They currently have the stock 245/40 front and 265/35 rear. I need to replace tires and am thinking about going to either 255/40 front, 275/35 rear, or 265/40 front and 285/35 rear. As near as I can tell, even the largest combination will keep me under 3% difference from stock.

Has anyone done this and what was the result. I'm assuming that even with the larger combination that there wouldn't be any rubbing issues but I could be wrong. Also, does anyone have tire recommendations for either of these combinations?

 

I stayed the same size on the front and went with a 275/35 on the rear. It is about 1% different. I am running Vredestein Sessanta. Got them shipped to my door for $798.16. The tread design is wicked. They handle really well in the rain and the dry. http://www.performanceplustire.com/p...678#prodAnchor

 

And what do you achieve by altering the OEM tire sizes?

 

Thanks for the info. I'll check it out.

My thought though was that it would give me a bit more rubber on the road as well as reduce the slight amount of stretch you get with the stock tire size. A little less stretch may help protect the rims a bit more.

I'm not terribly well informed when it comes to tires and wheels so I'm certainly open to being educated. Do you have any idea?

 

OEM tire recommendations work well. Varying width plus or minus 10 accomplishes little if anything. Want performance? Get a decent tire. A good 245 mm tire will outperform a mediocre 275 mm tire any day.

 

OK, I can understand that. So are you saying that a 10mm difference is simply too small to make a practical difference in performance? What about a 20mm difference?

What about a good 245 tire vs. a good 255 tire, or a good 265 tire vs a good 285 tire in terms of lateral grip while cornering? Also, any idea if increasing the rear width relative to the front (ie increasing the rear 20 mm while leaving the front stock) will decrease the tendency to overstear?

I appreciate the info.
