Major tire tread on 225/70R19.5 G647 RSS
Posted by Michael from Santa Rosa, CA, US on July 28, 2008

I’m looking for someone to tell me what are the major tire grooves on this tire. There is two small skinny lines on the outside of this tire that go around this tire and needed to know if these are concidered a major tire groove or not.

A major groove is described as a groove that contains a tread wear indicator. A tread wear indicator is a "bump" at the bottom of the a groove that helps to visually tell you when the tire is nearing the end of its treadlife. The two "skinny" grooves you describe are not major grooves.


11R22.5 or 12R22.5
Posted by Roland from Jacksonville, FL, US on July 28, 2008

Would it be wise to use a 11R22.5 tire in place of a 12R22.5 for vocational vehicles such as a Concrete Mixer trucks in Florida? I have some concerns about the availablity of 16 ply 11R22.5 cap and casings. The other concern is the load capacity is near the max on a 11R22.5 for three axle trucks.

If the truck came with 12R22.5 tires when new, you are concerned about availability of the 11R22.5 LR-H tire and the loads you are carrying would nearly max out the alternative tire, I would have to ask why you would want to switch. ?? I would stick with the 12R22.5 size.


Tire rot
Posted by Warren from Walpole, MA, AF on February 23, 2008

Service TEch said I need new tires due to tire rot on the inner rim area. The tires are not that old and still have good tread on them…What is the story?

I doubt that the tire has "rot" on the inner rim but, it could be some sort of solvent or chemical that has done some damage to the tire. If there was weathering of the tire, it would more likely be in the outside of the tire since this is where it could get sun exposure.


295/75R22.5 Tires in place of 11R22.5 tires
Posted by scott from pelahatchie, MS, US on February 21, 2008

Can a 295/75R22.5 be used in place of a 11R22.5? I would be changing both steer tires…both tires are LR-H.

If you change only the steer tires to the LP22.5 size, you will be lowering the front of the truck about a half inch. I can't imagine that this would have any negative affects.


295/75R22.5 vs 11R24.4, which gets better fuel mileage
Posted by ron from anchorage, AK, US on February 14, 2008

I’m ordering a new truck and when specking tire size which size (should) get better fuel mileage? Tire size makes no differrence to my fleet, but will have to recalculate the rest of the drive train specs.

All other things being equal, the 295/75R22.5 size should give you better mileage. This is mainly do to the fact that it will make the vehicle closer to the road which is better for aerodyamics and the better for fuel economy. Also, we offer the Goodyear Fuel Max tire line in this size (G395 LHS for steer, G305 LHD for drive and G316 LHTfor trailer) and this will result in even better fuel economy for you.
