I'm running 275/35's on the front on a 9.5" wheel with a 15mm spacer and a 305/30 on the rear with a 10.5" wheel & 20 mm spacers. No rubbing or issues at all. When I first got the tires I was running the stock width wheels with no problems at all.

AZ

I'm thinking about getting these tires too...I guess that 265/305 combination is the best we can do?

Anyone know if that will cause too much understeer?

Anyone running 265/305?

sick

Not too sure about 265/305 but I'm running 275/305 without any understeer issues. Tons of grip with the RE-11s, can wait to go back state-side and auto-x.

Hmm... but that makes the heights different. I would like to avoid that and the only combination that will do that is the 265/305. It should be fine.

**DISCLAIMER** This post applies only to Bridgestone RE-11’s mounted on stock sport 19inch wheels and should not be construed, either impliedly or expressly, to apply to any other tire or manufacturer mounted on any other wheel.

I ran 265 up front and 305 in the rear all season without any problems. To adjust for oversteer I just played with tire pressure. The RE-11’s are a great tire that handle swings in tire pressure with real grace.

I believe that the 265/35/19 up front on the sport stock rim is a perfect fit.

However, the 305/30/19 on the rear stock sport wheel does not really fit. It's not that it's dangerous (I had seven track days and a season of autocross with no problems) or that it rubs, it is that the tire is so pinched you can't take advantage of all the rubber.

If you look at my fronts (265), I was able to wear the tire right to the tread indicator (the little /\).

However, I was never even able to come close to the tread indicator on my rears (305). Next time I will opt for the 285’s on the rear.

Please don’t read this post as saying that 305’s will not fit on our sport stock rims. They definitely fit and they look spectacular! However, it is apparent that you don’t get full use of the tread surface.

good post, +1 rep.

I have the 265/285 setup, I really wish I had gone with 285 F and R instead. Too much plow with the setup

Too much plow with 265/285? Do you have sways or adjustable coilovers? played with the alignment?

I'm pretty sure the lack of usage on the rear is because of your alignment

Here is the inbound side of the same rear tire. Thoughts?

Are the RE11's available in 285/19 Inch? Can't find them on the Bridgestone or Tirerack site. Would be nice to go up one size from the stock 275's that look stretched.

Yeah, I could sworn there were a couple people running 265 in the front and 285 in the rear.... I'll try to find a link

I got my 285/35/19's RE11's from Tirerack about a month ago. :tup:
