tire question
 

does getting bigger tires cause the speedometer to read inaccurate?

Yes, along with the odometer. There are several online calculators that will give you the difference, and here's one.

Yes, but as long as you are just going up a tire size or two, the inaccuracy will hardly be noticeable.

ok, good to know thanks guys

What size tires do you plan on running? Im also assuming you have the stock size now 235/75/15?

yeah i have stock now. i wanna get a 2'' suspension lift (maybe this onehttp://roughcountry.com/chevy_4wd_s10.html. ) not sure what size yet 30 or 31s with some cragar soft 8s.. whats a good fit with little to no rubbing?

I just got my crager soft 8's friday, ill have my center caps on monday and ill post pics of it before and after it will give you a good idea what it will look like, your trucks the same color as mine also.

I'm running a different size tire than stock. I even used the Tech2 scanner to program the new tires in, and my speedo is still off...at least compared to my GPS. When I pass the mobile "Your speed is...." things that cops set out on the side of the road, the speedo is off, but the GPS matches exactly, every time.

I put 205 50 15's on my 88 s10 2wd , my speedo read 135km/h when i was going 100 lol

i have 32x11.5s and my speedometer is off by 5mph. my speedo says i'm going 50 when i'm doing 55, figured this out with my gps =]
