ZeppoJeff Posted September 7, 2015 Posted September 7, 2015 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) Quote
ZeppoJeff Posted September 7, 2015 Author Posted September 7, 2015 I'm always nice Okay be nice and give me some help 😠Quote
Ekona Posted September 7, 2015 Posted September 7, 2015 235/40 and 265/35 would be my choices, no stretch and sensible sizes too. What tyres are you planning on running, if possible? Quote
Ekona Posted September 7, 2015 Posted September 7, 2015 Sadly I don't think they're available in the first size, might have to go 45 profile. Quote
ZeppoJeff Posted September 7, 2015 Author Posted September 7, 2015 Seems u don't get mpss in those sizes though Quote
Ekona Posted September 7, 2015 Posted September 7, 2015 (edited) How close can you get? I'm too lazy to look at the Michelin site Edited September 7, 2015 by Ekona Quote
ZeppoJeff Posted September 7, 2015 Author Posted September 7, 2015 I can get if I get 45 and a 40 Quote
ZeppoJeff Posted September 7, 2015 Author Posted September 7, 2015 I thought 245 was the minimum for a 9" though Quote
Ekona Posted September 7, 2015 Posted September 7, 2015 Bobbins. It's down to the manufacturer to decide. Michelin don't actually publish theirs, but as a rule I use Toyo and their R888 as that's a solid control tyre. Also happens that you can see the sizes easily on their website Quote
ZeppoJeff Posted September 7, 2015 Author Posted September 7, 2015 Awesome. So we are saying 235/45 and 265/40? Quote
brillomaster Posted September 7, 2015 Posted September 7, 2015 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? Quote

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. Quote
brillomaster Posted September 8, 2015 Posted September 8, 2015 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?

mouthwash Posted September 8, 2015 Posted September 8, 2015 (edited) Why are you suggesting different profiles on the front and back? That's going to look weird as funk. 245/40 and 265/40 would be fine in my non expert opinion but **** Ekona. Edited September 8, 2015 by mouthwash Quote
Ekona Posted September 8, 2015 Posted September 8, 2015 (edited) 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!). Edited September 8, 2015 by Ekona Quote
