So, if I have those on my '93 what are my options for uping size? I looked in the tire sizing thread but the wheel sizes started at 15.

 

Ya, you are better off getting a 15" wheel. Tires are cheaper.

 

def better off getting a 15" wheel. tires are cheaper and u get more tire choices

 

Yea, that's what I was thinking. Would I have to make changes to make my speedometer accurate though?

 

only if u go up a significant tire size

 

Not if you got a 225 again

 

WRONG!!!!!!

the 225 is the tire width, it has nothing to do with tire diameter. a 225/70r14 is NOT going to be even close to the same size as a 225/70r15. All that will be the same is the width.

 

Yea... that's what I thought. Does anyone have a good link for changing the speedometer reading? Or some more info about that.

 

225/70r14 is 26.4"...going to a 225/70r15 would be a 1" increase, which would cause your speedometer to be off by about 3.8%, so if your speedometer read 65 you would actually be doing about 67.5. Not really enough of a difference to be worried about in my opinion. If you want the closest possible diameter match a 225/65r15 would be 26.5" tall and that would be pretty much the same speedometer reading.

When I went from 245/75r16 to 265/75r16's my speedometer didnt change even though there was a 3.9% change. I tested it with my GPS.

 

Never mind on what I said. I am to tired to think. Going to bed now.
