19.5" Truck Wheels and Tires

I have a 2012 GMC Sierra 3500HD SRW with 40K miles and tow a 16K 5th wheel trailer. I tow about 15K miles per year.

I am within specs for the truck and trailer, but the OEM Michelin LTX A/T2 265/70R18/E tires are wearing and will be due for replacement soon. Commercial 19.5" tires have longer tread life.

I am considering changing to 19.5" wheels and tires. I will probably buy the American Force Beast 19.5" forged aluminum wheels.

I am unsure if I should go with 245's or 225's. I like Michelin tires but was told by Rickson that they have road noise complaints with the XDS2 tires. My second choice would be Bridgestone M729F.

I'll also install Centramatics to keep the wheels balanced.

Any tire suggestions or advise?

A lot of posters on Turbo Diesel Register. Com has installed the 19.5" tires and rims on their trucks to allow them to pull heavy. Some are running the TOYO tires such as M608z and others are using the Goodyear G622. They claim that the Toyo’s are real quiet but I have no data on mileage life for them.

Check out some of the truck camper forums. The 19.5" tires are very popular with those folks.
Try RV.net and go to their truck camper forum and ask questions. Very knowledgeable group.

drfife,
Don't forget that if you change the diameter of the tires that you must get the ECU recalibrated so that the speedometer, ABS and transmission works properly.

Russell;

Sorry I did not get back to you yesterday, but I was very busy and did not have time to do a search.
Today I did and found three current threads on the subject. These should explain what size tire and why they are using them. I hope this helps?

I converted to the Alcoa 19.5 from American Force Wheels. Had them now for a couple of years on my 2007 and pulled great with 4.10 gears. Now I just traded up to 2014 F350 DRW Lariat and they are currently on the 2014. Tire size is 245 70 19.5 I haven't towed with them on yet but I am thinking of going to a 4.10 gear over the 3.73 due to the increase in tire diameter and weight. They are heavy. I have a trip in September planned with the 5er, which BTW is a 2008 40FT Endura Max Gulf Stream.

warrstang331,
Believe you will be just fine with the 19.5s and the torque of the 2014 engine--the differences in the 6.7 from the 6.0 are tremendous, and you won't have to worry about the truck not handling the bigger tires.
Joe

Wingnut,
Thanks for that bit of info. I will post how she tows with the taller tire and 3.73 gears after my trip in Sept.

I cannot find Alcoa wheels on the American Force website.

Which model 19.5" wheels did you order from them?

True, but don't confuse tire diameter with wheel diameter. The "tall" LT245/70R19.5 is the same diameter as the LT275/70R18 that is standard on some 250/2500 SRW pickups with about 627 tire revs/mile. And if you replace LT275/70R18E tires with LT225/70R19.5F or G tires, the 18s are taller than the 19.5s.

To determine the difference the tire size will make in your speedo error, use the percentage difference in tire revs/mile. Trying to use actual tire diameter a lot less accurate. The revs/mile specification is available for most tires in the tire specs for that size tire. For example, check the specs for the Michelin 19.5 XRV tires at this link:
http://www.tirerack.com/tires/tires....omCompare1=yes

For the typical 3500 dually, LT245/75R17 tires are stock, and they have about 663 revs/mile. LT225/70R19.5 have about 646 revs/mile. That's 2.6% difference in your speedo/odo/ABS/tranny shift points, etc. Or less than 2 MPH difference at 70 MPH. Yeah, you can pay to have your truck's computers recalibrated to correct that 2.6% speedo error, but most just ignore it. The stock calibration is often off by that much.

Note that the revs/mile for the same size tire can vary by a few revs/mile, depending on brand and tread. So use the revs/mile spec for your exact size, brand and tread.
