Help me to settle a disagreement on tires

My son-in-Law, who worked for Discount Tires a few years ago, is telling me that the 225/75/16's that he has on his Ford Galaxy car are the same tires that are put on Ford E350 vans, and they'll be fine on my 8,000 LB E350 Coachmen 21' MH. I say no, there has to be a difference. Can someone set us both straight on this?

Are either or both "P" 225/75/16 or "LT" 225/75/16 ?

If both are the same prefix letter then your SIL is right. If not you maybe right.

Car tires are a lower ply tire then when you need on MH. I would ask for a 10 ply tire with 4 ply sidewalls that will help keep MH form swaying on the road.

If there are LTs on the car, they are way better than the original equipment tires that came on his car.

But the final proof is the load weight rating on the side wall .
Max load at max inflation, HAS to be on every tire sold . You just have to do the math.

All LT tires are not created equal. Most I see are load range D. Tires on a motor home should really be load range E. This will result in much less sway in addition to higher capacity.

Thanks for the quick reply guys. I checked the tires on both. His are D's and mine are E's. I looked up a few tires and Discount Tires suggests GT Savero HT2, LT225/75/R16-115R-E1. What do you guys suggest?

Greg.. you do know that tires today do not have 10 plys and 4 plys on the sidewalls...right?

Dakota... from what I've heard and read, those tires are probably just as good as those that cost twice as much..

As noted there are different load ranges... You need the higher range tires for the motor home.. Put P (Passenger car) or LT (light truck-pick up or small van) and you are going to be very unhappy.
You need Truck or Motor home (There is a difference) tires

Truck give a rougher ride

You need a load range at LEAST as high up the alphabet as what you are wearing now.
