Try the website for the tire, many manufactures have it listed on their sites.

 

okay so i drive the car and everythgin is fine no enine light now i adjusted the tire size and the engine light came on any one no what i should do

 

Use the Xcal-3 to read the code.

 

tru hahah

 

deek. just read the code with the sct x3 and then clear it. then re-tune the pcm with the brenspeed tune. all should be good after you clear the light and re-tune.

 

ill go try it now

 

deek, we know you're excited but you need to calm down, lol. take a breath, sit back, and think about your problem. I'm sure you can figure some of this stuff out.

 

haha what r u like 5?? with all these hyped up questions and 2 word posts lol..

heres how you fix. go back in and change the tire size back to what u had it on ya num nut! you prolly wont even notice or oprolyl wont be a difference really.. dunno what dimension the tire option is changed by but you still have 18 inch wheels so i don't think its too big of an issue..

 

That's true. I thought the same thing but didn't mention it. Unless you bought some seriously wrong sized tires, there is no need to readjust for them. I'm running on 20's and my speedo is still accurate at 65mph (freeway radar confirmed).

 

hahah i know sorry guys im a little nuts today alot goin on with other sh*t too haha but im all good now haha i h ave pics ill post in a few secs this thing is really sweet lokking under the hood and also it hauls a**
