I am getting ready to get some new tires for my 24' Motorhome and the size is 8.75 x 16.5
Even thought the two in front are near new I am considering replacing all six and using one of the current fronts as a spare and keeping an extra in the garage.
Here are the tires I am considering
http://www.tirerack.com/tires/tires....875QR65VHT824& as they are good tires for a low price and the current tires (Michelins) have rotted before being used up anyway.
When I look in the owners manual it calls for Load range E tires for the front and Load range D tires for the rear.
Current tires are all range D but I have never really loaded it.
Here are the weights of my Motorhome
G.V.W.R 12,500
Curb Weight total 8485
Allowable additional weight* 4015
G.A.W.R front 5000
G.A.W.R rear 7500
Curb weight front 3920
Curb weight rear 4565
Allowable weight per axle Front 1080 Rear 2975
*Allowable additional weight includes all options and accessories, passengers, waste, water, food,supplies, clothing, other personal cargo, etc...
Here is my question for the experts at this stuff.
The tires I am considering are load range D with a Max load of 2350 pounds so on the rear they are perfect, but on the front they fall short of a fully loaded situation by 150 pounds per or 4700 Max load instead of the possable 5000 the vehicle can carry.
I do not think I will ever come close to overloading this 24' airsteam and wondered what consideration I should give this matter if any.
Tires in this size range are available in D and E ratings , but I would have to mismatch them to achieve both D for rear and E for front.
I do not want to have mismatched tires as the factory recommends just to have 300 more pounds load capacity that I will probably never use.
And I am also asuming that if the tires are under rated by even a few % they will be suitable at max load as it is.
I hope I made my thoughts clear and please feel free to give me your opinion.
Thank you
