I currently have 31x10.5x15 on my 95 yj. If i go to 18 inch rim keeping the same size tire will i encounter any new issues? Thanks for any help i can get.
I had the same line of thoughts.Defcon 1 said:Do you mean keep the same tires you have now? Or get the same size tires to fit the new rims?
I don't believe a R15 will fit an 18" rim, and I don't believe they make 31"x10.5xR18 in any normal tire type, maybe a street/road tire will come in that size but I don't know about any off-road or all-terrain tire.
Usually the rim size of a truck tire is half of the total diameter of the tire, to keep a larger sidewall length. That's why 30's are common and made to fit 15" rims. They usually don't deviate too far from that formula. An 18" rim with a 30" tire would only mean 6" of sidewall, that's not a whole lot of rubber. I'm not trying to stir anything up, just curious but what are your reasons for such a large rim size?
