Help!

I am running 195/60/15 tyres (615mm diam) on 15*6J genuine Subaru alloys but need two new tyres (one puncture ) Brightside = good time to go to 17's.

Should I go for 225/40/17 (612mm diam) or 205/45/17 (616mm diam) I thought that 17's on a classic (I have a MY99 Sport) should be on 40 profile tyres...

I once tried some 225/45/17 tyres but the rubbed on rear strutts so think are too wide - how do I work out offset too???

Thanks, Jon

Ps. have been using this tyre diam tool

On a classic the standard tyres on 17" wheels come as 205/45/17 but this limits you to a few manufacturers e.g. Pirelli. Most people (including myself) go to 215/40/17 which means you can get Toyo T1-S, Goodyear F1's, Bridgestones etc and keep a very similar rolling radius (might under read on the speedo which is better IMHO).

Cheers Simon,

Just playing with above tool...do you think I could get away with 215/25/20's

Hi Rusty

I had 205/45/17 P zero;s on my RB5 and at the time Prodrive said they were the optimum tyre size. I have seen others with 215/40/17 Bridgestone Potenzas SO2 's which do not require any mods. I am going tofit 225/40/18 to my Sti8 (96 miles now !!)soon providing I can get source some Prodrive OZ.

Cheers

Hi Dave,

looking forward to seeing your new stead

Don't hang about for your dealer to source you Prodrive Oz's when you can get them from Scoobyworld

Hi,

I ran 225x35 on 18s with PZeros which preserves the rolling radius I believe (unfortunately they don't fit my STi type UK so I'm going to be posting a query re. what I could upgrade the std 17s to & what my Radius multispoke in silver 18s could be worth.
