Once I saw what dsbear installing 275s
all round on similar Class A. So now a bit curious as to what we have on our 2006 Damon DP which are 235 rear and 255 front as being less than might be.
Please any comments appreciated.
The attachment I have was sent by Thor Warranty for our 2006 Damon.
It supports what we have currently on the DP 2006 Damon.
So now, I am curious as to any changes / recalls for larger tires to be used.
Important in the discussion of tires is the second series of numbers mostly 70 or 80 for the Astoria motor homes, it is part of the tire spec and determines along with the other numbers the tires weight handling ability.
There was a recall for 2005 Astoria Pacific Waldorf editions related to front tires being under spec for the weight of the coach Damon Recall No. 05-115 the national highway traffic safety Admin hotline 1888-327-4236 or safercar.gov. Have your vin handy.
My guess is that with the larger front tires you have a comfortable safety margin as far as weight. My 2006 Astoria 3595 single slide out. has 235-80r-22.5 all the way around. So your 255-80r-22.5 has 530# more load capacity per tire by my Michlelin RV Tire Guide. If you do not have this book it is very informative and explains everything you need to know about RV tires including how to do a weight test.
I did do a weight test on my coach. I did not have driver and copilot or water or food or clothes in the coach
My weights were 8600 front and 13860 rear. So for my tires having a 4675 max at 110 I am OK but am not sure how much weight the clothes, food, and water will add to the front.
I would be more comfortable with the larger 255-80r-22.5 tires but am not sure they would fit. My tires were just replaced in OCT of last year so we intend to make due with what we have and put the coach on a diet if we have to
I intend to weigh the coach on a wheel separate scale if I am at Escapees when they have their scales out. The rear duals can handle 7530 at 90psi so we are probably okay and can add more air to take the capacity up to 8820 at 110 psi. So the info from the scales tells me that I need less air in the dual rears than I do in the front. I have only driven the coach 300 miles or so but it seems to handle well. I drove it with 85-90 psi all around what the MH dealers prep person thought would give a soft ride and my 90 rear and 110 front and really could not tell a big difference. The coach had the clothes loaded with the second inflation. Hope this is helpful. Dennis
