Gmc 2500hd Looking For Tires....

[Anger Management]

sorry folks....they are 16" rims on my truck. My mistake.

If I put 265 or 285's on my truck verses the 245's, is the speedo off by a lot?

Thanks again,

1. Go to an 8 or 9" wide wheel while you are at it. You will see a DRASTIC improvement in handling, braking, and towing stability.

2. Its tough to beat BFGoodrich All Terrain KO tires. Period.

3. 265 series tires will fit no problem.

4. 285 series tires will fit with front torsion bar tweaking, BUT, will also depend on if you go to a wider wheel and the associated backspacing. These really fill up the wheel well nicely.

5. Hypertech and Diablo Predator Power Tuners will change your speedo ratio for your new tires, and have other benefits. Do a search here on OSO; lots of info. Your dealer can also program in your new tire size into your stock ECU to correct speedo and shift points.

Going with Outlaw II same as on the boat trailer. Have to keep everything uniform. Don't want to look like a geek going down the road or when pulling into the ramp. Remember its all about looking Good.

Just check tires on new truck.

Tires from Factory are Bridgestone.
265/R70/17 are 31.7 in diameter
265/R75/16 are 31.7 in diameter (note middle #)

speedo should be same if you change to 265. 285 is width of tire. Middle number is height from wheel to tread height.

I really like the Michelin XC LT4 tires that Sears carries. They are made for Sears by Michelin. I have the same truck in an '06. I'm starting to put them on my other work trucks as well. Check them out.

I put Nokian Vatiiva A/T 265/75R16E on my 2003 2500 Yukon XL and I am very happy with them. Might want to do an internet search on them, they get good reviews. Fairly aggressive looking and acting but very quiet compared to the Bridgestone's I replaced.

I believe I am off 7% which is appx 4.2MPH at 60MPH running 285 series tires. Keep in mind going up tire sizes will decrease fuel mileage to some extent.

Keep in mind , as well as the speedo reading low , so will the odometer. Check MPG with gps. I think you will find very little difference. You could also add 7% to your miles traveled before computing milage.

I will be keeping the stock wheels on the truck, and I'm leaning on the 265/75R16E tire size. The 245's are too small for my liking, and I really don't want to mess around any more than I have with the torsion bar to fit 285's. I have already had the torsion bar cranked up by the dealer so the front of the truck is a little closer to level.

I just put 285's on my 2500 crew cab and they fit fine without doing any changes to the suspension.
