I have a set of 8J X 18 ALLOY WHEELS with 225-40-18 tyres fitted these don't quite cover rim edges.

 

Can I fit 235-40-18 or 245-40-18 size tyres so they will protect the rims.

 

I purchased wheel and tyre set online for £650 the 4 wheels alone are £450 meaning the tyres are cheap £50 each which I would like to change to Continental.

 

Any advice on what tyre size I can go to on 18inch 8j rims please?

are they genuine extremes? 19s?

 

im lowered on 235-40-19 and cant go any wider as they wont fit. i have no rub at all but no way i can go 245. 235 gives a nice lip 

 

 

Thank you very helpful mine not lowered will this make any difference?

235 is wide enough on 19s, lowered you wont get rub you might be able to go to 245 but personally i dont see any need

I just put 235 40 18 Pirellis on mine and there are no problems. I have improved ride quality, but new tyres does that

Thanks OzGordo
