Are there any issues with putting stock 18's on the back instead of 19's? Will this effect the speedometer or odometer at all?

Was thinking of getting two stock 18's to put blizzaks on or just in general to have a solution to get tires rotated so that they last longer than 18k miles, which my last 2 sets of Continentals lasted. I just basically commute 50 miles a day highway. They should last longer than that IMO.

 

Your speedometer will be off with 18" tires if you don't use one that's the same height or diameter as the 19"s. Which is about 26".

 

the correct fitment would be 255-40-18. hope that helps.
255-35-19 = 26.03
255-40-18 = 26.03

 

But that still eliminates the ability to rotate front to rear.

 

I understand that putting 18" all around is fine, no problems.

 

You could put 17'' rims all around as long as the offests were good and the OD of the tires was at or near OEM.

 

in the manual it tells u to use 18's all around for winter tires. jim

 

i have 18" all around for winter. after doing some calculations, aka, finding a website, with my 18"s I am actually going 59.3 when my speedometer says 60. just food for thought.

p.s. i am runn 255/40/18 all the way around.

 

Matt, dont you have rubbing issues with the 255's on the front?

err... sorry. didn't mean to type 255.... what i actually have all the way around is:

225/40/18.

 

So, is it ok to run this size tire all the way around? with no issues and lowered?

 

Note his correction in post above..... he is using 225/40/18... I believe that 255/40 in front would have rubbing problems....
