Question Widest 16" tire to fit WRX 6.5" wide rim?

Hello all,

I'm thinking of replacing the RE-92's. I don't want to go to 17" rims just yet. So, what is the widest tire size that would fit the 6.5" WRX rim?

Thanks,
JahWind

I'd stick with the 205's. Miata autoxers run 225's on 6.5", but the tires start looking a little strange. It may work for short stints at the track, but I wouldn't run that way on the street. The tires aren't really designed to have the sidewalls taper inwards to meet the rim.

There are plenty of sticky 205's to choose from, and they're cheaper than 225's .

Yeah, here's some 215 numbers, but I'm not going to try and put it in a nice table because that [ code ] font really SUCKS! Just assume the same column headings. It turns out to be simple: neither the Yokohama AVS Sports nor the Bridgestone S-02 Pole Positions are available (at least from Tire Rack) in a 215 for 16" wheels.

215/55ZR16 7.9" $158 Dunlop SP Sport 9000

BTW: the 215/55 is a slightly taller tire than either the 205/55 or the 225/50 and will throw your speedo/odometer off by about 1%.

The price of the Dunlop 215 is higher than the 225. Also, I just noticed that Tire Rack is having a sale on the Dunlop 205/55 for only $115!

Jon,

Great info, thanks again. You even found a sale that's going on. Were you planning a similar upgrade? I found a calculator, http://www.secret-secret.com/turbo/D...turbotire.html
which give you info to as to the % that tire choices would effect the speedo. The SP 9000 sounds like a killer deal!

I think what you want to maximize is tread width, as opposed to overall (section) tire width. Here's some numbers I was able to find on this issue:
Code:
           Tread  Tire
  Size     Width  Rack  Model
205/55ZR16  7.2"  $130  Dunlop SP Sport 9000
205/55WR16  7.1"  $161  Yokohama AVS Sport
205/55ZR16  5.9"  $156  Bridgestone S-02 Pole Position

225/50ZR16  8.1"  $146  Dunlop SP Sport 9000
225/50WR16  7.9"  $161  Yokohama AVS Sport
225/50ZR16  6.5"  $180  Bridgestone S-02 Pole Position
Neither Michelin nor Pirelli publish tread width data, so they aren't included here. Both Yokohama and Bridgestone say their 225/50/16 tires can be mounted on rims as narrow as 6" (Dunlop's site doesn't address the issue, but I assume it's true for them as well). However, they all agree that the best fitting tire for the WRX's 6.5x16 wheel is a 205/55/16.
