"Truck" versus "RV" Tires

Trying to get the best ride I can on my Safari with Torselastic suspension. Gone the Koni route and they are being adjusted now.

We have new Hankook 16 ply 275 70 R 22.5 tires on the front and almost new cheap Chinese (Linlong) tires on the dual rears.

Team at Redlands truck are saying I should consider Michelin or Goodyear RV tires rather than the truck tires. They say it would make a 20-30% difference in ride. Planning on replacing the Chinese rears (even though almost new) later this year.

Anyone have any comment on the ride quality between "truck" tires (Hankook, Toyo, etc.) and the Michelin or Goodyear. Is there a real difference and it is worth the extra !00-150 per tire? If I do buy, can I put 4 new on and put the new Hankook on the rears?

Any comments would be appreciated.

Thanks

I doubt you would feel any difference if you changed tires. Some truck tires require higher inflation pressures to carry the load but it's not day and night difference.

If it were me I would use the tires as long as I safely could.

The difference is in the formulation of the tire. Truck tires are designed to run loaded and unloaded, RV tires are designed to run under constant load. (According to Mich tire)

I run truck tires on my Dodge Ram tow vehicle, and my tire dealer said that if I "needed" a softer ride, simply drop the air pressures about 10-12%. I even contacted Firestone Engineering and they said it was okay to do this. We have good ride and excellent wear from Firestone Transforce HT tires.

Tiires

Two years ago I replaced my Michelins with Toyos on our '04 Sea Breeze.
No ride difference. I like the Toyos better - a more solid, well-built tire. Softness can be adjusted by inflation pressure, as mentioned earlier.

According to Michelin, RV tires have more UV inhibitors because RV tires tend to sit for longer periods.

Some truck tires in the same size/load range as RV tires are designed for delivery trucks and have stiffer sidewalls to better withstand curb scrub. Therefore, RV tires may (let me stress again - may) ride better than some truck tires.

I question the "adjustment of inflation pressures to soften a ride" recomendation. The inflation pressures should be what is required to carry the weight put on that tire plus 5% for safety as listed in the tire manufacture inflation/weight guide. If you lower that pressure to soften the ride and get below that required pressure for the weight on the tire then the tire is going to overheat and be damaged and can possible fail and have the dreaded zipper flat. Becareful of who you talk to at a tire dealership because there are a lot of unqualified people that work there. Nobody should be telling anybody to lower their tire pressures below what is listed on the inflation/weight chart.

You lower tire pressures at your own peril as well as others sharing the roadways with you.

I have just recently moved a pair of 2yr old Toyo M143's from the steer axle to the tag, and moved the 1yr old Michelin XZE's to the front.
Same air pressure in both sets of tires. The Michelins have at least a 20-30 % better ride !

According to Michlein they will also last 10 years. Yea right !!

See if they will give you your money back if they don't ride 20-30% better.
Just a guess, the answer will be NO !!

But they then tell you to run the tires regularly to get the UV inhibitors working.

Either Truck or RV tires, my butt is not sensitive enough to feel the difference.
Or the ride % difference in 10 PSI in a RV tire, or different make, that some claim they can.

That may be due to the smooth ride a air bag chassis gives me.
Or my old age has caused the butt feelings to lessen in sensitive.
Maybe I will ask the Dr. about that on my next visit. That is if I can remember to.

But I do run the G670's that have a 7 year warranty on cracking.
Michelin RV tires has a 0 days warranty on cracking.

Long Haul 'truck' tires also have lower rolling resistance... But they are less capable off-road. Everythings a trade-off.

Hit the scales

I do not like adjusting air pressure for ride. If you check the manufacturers tables for the tire size, the recommended pressure can vary considerably based on the axel weight. That is why I think it is important to hit the scales, get a front axel weight, total weight, and rear axel weight, then use the tables to get the proper air pressure.
