sorry for the n00byness but im looking to get 18" wheels... how do i know what offset to get?
looking at getting size 205/40-18 tyres or 215/315-18 tyres for the 18" rims.

thanks for the help

 

+42mm to +50mm should do.

 

depends on the rim width also..

 

I'm running 18x7.5 Konig +42mm offset with 2" dropped PSS9 w/o rubbing. The ride is slammed and you could not fit a penny in the rear flare I've track it too.

 

you're right. Don't use a 10.5" width rim!!


7-7.5" width is most ideal

 

thanks for the info guys.. didnt realise how much stuff there wasabout tires


well im looking for 18"s.. 205's or 215's? what width and thus offset ok with this size rim?

 

i'd do +45 215/35/18's on 18x7 or 18x7.5's

 

I would love to hear what you guy's think about a 17 inch wheel with a 38mm off set and 215/45 for tires with H-sport springs. Alex at Tire rack tells me that they guarentee that they will fit if you do some (lip work). I don't know if that means cut a little away from the plastic linner or roll a base ball bat under the fender and tire (joke) . I don't mind dremeling some plastic but I don't want to do heavy body work of any kind. I just don't want to make the wrong choice and want to know for sure before I buy the wrong wheel and tire. I'm looking at ASA AR-1s with the goodyear eagle F1GS_D3s. What they offer for the mini is a 42mm off set with these wheels but the lip is to shallow so I plan to go with the 38mm off set which they offer in the 18 inch AR-1. I want the 215/45 for a little wider tire and a little more rubber between the wheel and the ground. Do most Mini owners get as worked up as I do over such things? 05/Cooper S,

 

Have no fear, dremel it clear!

Thanks Alex, I'm sure you deal with people like me every hour. Could you explain to me the size difference I will get going from a 205/45 pirelli run flat to a 215/45 Goodyear Eagle F1GS-D3 in terms of width and side wall height. Also did you ever look at that post about the White ASA AR-1s? Could you tell me what size you think they are. Thanks Alex! you da man.

 

215/45 Is 1/2 inch wider and 4/10th of an inch taller than 205/45.
