Even though both sizes were load range E on the 3/4 ton, the 18 inch tires had about 400 pounds more load capacity. So with the tires and 1 ton truck I now have more capacity. As many of you know, when you finally pull the trigger on the camper it tends to be larger than originally planned. Even if we don't upsize we now have a greater margin of safety.17 inch wheels vs 18 inch on tow vehicleWe have sold our TT and the 1/2 ton truck is next. We are planning to purchase a 5th wheel in the 10000 pound range. Today we shopped Chevy Duramax 3/4 ton trucks. Looked very capable of handling the job. Question is: Some had 18 inch wheels and some 17 inch. Both were load range E. Door jam stickers were the same. Would one be better than the other for towing the 5th wheel? Seeking advice before purchase. Thanks
