Another tyre size thread

Recommended Posts

Planning on getting new alloys and what I have found is 18" 9j front and 18" 10j rear.

What would people suggest ideal tyre size for these? The wheels sit as the original rays do with spaces installed so no need for stretch.

Any help would be nice

(Please be nice ekona)

wont that have problems with the TCS? surely the rears would also need to be a 40 profile to match the fronts, a 35 on the back would be too small a diameter?

Looks like 2% between the two tyres (fronts -1%, rears +1%) so TCS should be fine.

 

We are going 40 on the rear ;) But no, no need to match the 45 on the front as we've gone for a 30mm width stagger rather than OEM 20mm.

I'm still not convinced... difference in rolling radius between a 225/45 and a 245/45 is -2.66%. The difference between a 235/45 and a 265/40 is only -0.07%... so you'd get TCS issues surely...

 

whats wrong with 255/40 and 275/40? would sit nicely on 9" and 10" rims, keep the stagger, keep the same rolling radius to the original sizes?

Why are you suggesting different profiles on the front and back? That's going to look weird as funk.

Why? OEM tyres have different height sidewalls anyway.

 

If anything, those sizes will be equal (well, 0.25 of a mm!).
