I have a 32ft 2005 Dolphin LX. The Dolphin specifications brochure lists the Michelin tire size as an XRV 235/80 and the sticker inside the closet with all the model and serial numbers list the tire size as a 255/80. I can’t remember what was on the RV as I have changed tires last year. I am now running a Yokohama 245/75 and at 100psi it seems to ride a little rougher than I think is should. I am wondering if I should have stayed with the Michelin XRV for a better ride. What are other 32 footers running out there? Opinions appreciated

100 psi sounds high. That said, You need to weigh and then adjust per the tire tables.

We carry a lot of stuff and front tires are usually in the 85-90# range. Rears are usually at 95-100#. Weighed 4 corners individually in 2012. LF 3350....RF 3400.
LR 7100....RR 7600. Using this info Henderson's in Grants Pass, Or set Fronts @80# and Rears @ 95#.

These tires are Bridgestone R250F; 245/75R 22.5 G/14pr. Max 110psi

We have a 2005 Dolphin LX 6320 w/ W22 Chassis. We run 235/80R/22.5 XRV with Nitrogen @85lbs. front and 90lbs. rear. Ride is Superior.

Thanks for all the tire input. Tire Dilemma Update: The store that sold me the Yokohama RY103 245/75 R22.5 tires said to inflate to 100psi all around. When I went back and complained about a hard ride and considered going back to Michelins at considerable cost, they suggested maybe lowering the pressure and try that. So I weighed the steer and drive axles and used the Yoko inflation table calculator for that size Yoko’s and they recommend 80psi for the steer axle and 85psi for the drive axle. Sounds kind of low to me. Will probably add 5psi to those values and see how the ride turns out. There is a huge difference between a $10.50 scale charge and a $3500 bill to return to Michelins even though I think that would have been the better choice in the beginning.

Thanks again for the input…Bill 2005 32ft Dolphin LX / 2014 CRV toad...

Bill, why did you not go with Michelin?

Absolutely set your pressure based on individual wheel weights and tire manufacturer settings. We had the same experience when we bought ourMH last year. Put on new Toyos all around and dealer had them set at 110. Rode horrible after weighing and consulting Toyo chart we dropped fronts to 95 and rears at 105. Did the trick and tires are doing great.

Fred and Bonnie, Economics New set of Michelins over $4100. New set of Yokohamas $2935. Difference..$1165. That’s a lot of gas money. However, I have to admit the Michelins are the Cadillac tire, but come at a Cadillac price and probably give a little better ride.
