Replacemet Tyre Cost - Xr6t

[turbo_nick]

is it true you need to have your speedo recalibrated? is this something the ford dealership must do?

between 17" and 18" tyres do you mean? I know you have to between 18" and 16" so I assume you would have to get it done.

I can't see why you should have to. The difference in the rolling diameter between 215/60/16 and 245/40/18 tyres is negligible. Same goes for 245/35/19. Legally, you could even put 20x8.5 rims on your car with 255/35/20 rubber! hehe

Anyway, my speedo is pretty much spot on with 19s, although it was out of whack with both 15s and 17s.

I'm sitting here and thinking: you poor bastards! hehe My Falken 245/35/19 tyres cost me less than what most of you pay for a set of 245/40/18 tyres! Not that I'm rubbing it in, just making an observation. hehe

I phoned up the local Dunlop dealer. The dealer advised the following prices, also stating that you won't get them much cheaper as the markup is relatively small.

SP3000 235/45 ZR17 @ $282 each

SP9000 235/45 ZR17 @ $415 each

SP9000 245/40 ZR18 @ $580 each

Dunlop do not make a 18 inch tyre with a SP3000 rating, so for 18 inch wheels your onlt option is the SP9000 245/40 ZR18. The local dunlop dealer also advised that not all tyre places have the facilities to change tyres (in case of a punture) for the 18 inch wheels of this width!
