Help with tire and rim sizes

[Mustang_1]

Need help with rim and tire sizes, I screwed up and ordered the wrong tires, 245 45 zr 17, correct for factory rims, I have 17 x 9, but my new rims are 17 x 9.5, anyone see a problem with that, anyone have a web site that checks these sizes and so forth

They will fit fine;however, they will be a little taller and wont lay across the lip of the rim. Hard to explain.

Go to tirerack.com. You can search by tire size and then click on a specific tire. Then click the "specs" button and you will see all of the dimensions, min./max. rim width, overall diameter. ect...

you can use those tires...but u may wana get some 255's or even 275's for the back

ps leave smaller ones up front, less rotational mass
