tire size's yet again

Post by newbie »

Hey guys! i'm new to the site and 4x4 the truck thing. I'm picking up an 02 4x4 crew cab ls soon and want to beef it up a little but am not sure about a lift. I just got engaged and am looking for a house so budget is tiny. It will be mostly for pavement, but I have a tendency of finding empty construction sites, fields, and the occasional quarry up north to run around in so I need some grip.

From reading around it sounds like I can clear some 30x9.50's on the stock rims without to much problem.

I'm coming from a background in low fast and sharp corners HELP!!!!!

Stock rims and no BL = 30x9.5's Depending on the tire they may rub slightly, but nothing cranking the torsion bars a little won't cure.

Anything bigger (or aftermarket rims with less backspacing) would require a body lift.

Unless the Crew's sit a little lower than the Blazer's, you should be able to clear BFG A/T 30x9.5s without any rubbing at all, depending on if you front suspension has settled or not...

My Blazer was fine until I put the brush guard on... Now I've got little points in my fenders :)

I think the CC's do sit a little lower in front over the wheels. :( I run 235x75x15 BFG AT's and had to crank up the front about 2" for adequate clearance. I compared to a friend's 99 Blazer here locally and he is able to run identical tire-rim combination with no trouble. New my tires measure out at 29.0"x9.1". (from Bfg website) Since I did crank no more problems with the tire lugs catchin the inside lip of the fender on sharp incline or severe bounce turns. :bounce: :thumb:

Yeah yeah. Good for you! :kick: My CC came with 235x70x15's. :( After I put the 235's on I found out why. :cry: Oh well, at least it taught me the value of a tb crank. :wink:

Who ever had mine before me put 255/70R15's on mine. Looks ok BUT I'm not real happy with it. I prefer stock sizes (I drive 99.99999999% paved) so an agressive sized tire is not for me. Mine came from Factory with 235/70R15's. The diff is about an inch in height and may account for perceived low gas mileage. The odometer shows about .92 per mile by mile markers. I have a couple near me that are specially calibrated by MSP for speeding measurements so I know they are accurate.

The 235/75s was an option in '02. Mine was new, no factory sticker but, only had 600 miles on it. They came with both tire sizes.

Wow I didn't realize that the 235/70's are almost 1" shorter than the 235/75's.

235/75's overall diameter 28.88

235/70's overall diameter 27.95

I ordered my truck with the 235/75's.

Oh and I got 3.42 gears also

Actually BFG AT's are listed at 29.0" tall by 9.1" wide on their site mounted on a 6.5" rim. I think they are a little taller than some others the same size because they are LT (light truck) tires and the tread is deeper than some others. I also like them cause the carcass is beefier than some others. (3ply body and sidewall plus 2 more plys under tread and with rim reinforcement also) :thumb:

Well I guess you can't link directly to the tire calculator directly you have to go under info center
