2nd Gen Non-Engine/Transmission Taller tires for 2500 2wd??

[bkroupa]

I have 4. 10's & either need to swap gears or run a taller tire. What's the tallest tire I can run on the stock rim in the rear?

What's the tallest tire that'll fit the front so I would still be able to rotate?

33" or 285x75x16 or 305x70x16 all 33" equiv.



invest about $350 into a SuperChips diagnostics/tuner meter, and you can re-calibrate your speeding meter to the new tire height.

I went to 34" on mine, this gave me 10% on the speedo according to hand calculation. Truck works a lot better with this ratio.

I took off the Dualies because the ride was beating me and the wife to death. Installed white spoke single wheels all the way around. Wider tires on the rear, but all 34 ".

as soon as these michelins wear out, I am going to a larger size on the 99. But the biggest I've been able to document from the archives on a 2wd without rubbing is 265's. I am also a little concerned that the spare will fit (with the mag-hytec cover on the Dana 80)

285's

My first 45,000 miles were with 285's Load Range D that gave an approximate nine percent speedometer/odometer error. Thinking that I needed Load Range E tires to more safely carry a camper, I replaced the 285's when worn out with 265's that were the largest size I could find in Load Range E. The speedometer/odometer error is only two percent and the tires look like they belong on a Toyota or something. There is a big difference between 285's and 265's. The 265's look so small compared to the wheelwell size and the nice fit the previous 285's made in the wheelwells. The larger tires slowed down the RPM's at 70-75 mph to below 2000 rpm's and generally gave a better ride. Next time, I am going back to the 285's especially in light of the fact that some are now made in the 'E' range. I regret getting the smaller 265 tires and they are still larger than the stock tires!!

2WD

I assume 265's are as tall as I can go on the front?

I just talked to discount tire & they said 285's fit 2wd drives all the way around with no issues on stock rims. I know the stockers are pretty narrow, but I may go this route with their full warranty.

If you are looking for height, the 255/85 16's are slightly taller then the 285/75's. They are also a bit narrower - not sure where the potential rub points are on the 2wd's but the narrow width of a 255 might help. I couldn't find 255's in anything higher then load range D though, if thats a factor for you.



Also, if you have the mag hytec rear end cover, I have heard you may have clearance issues with the spare.



Good luck, and let me know which way you decide to go and how it works for you. I'll be facing the same decision in a few months.

Thanks, I'm looking at the 255's also for the better rim fittment & gearing. The Coopers look pretty good, but the Michelins & Bridstone Revos are the favorites. A "D" load rating should not be an issue for me, although I've noticed the guys with the E rated tires sure seem to get a lot of miles out of their tires
