88 Bounder Tires Question

The tires I have on the 88 Bounder currently are like new tread wise but they are seriously weather cracking on the side walls---So I guess I'm going to have to pull em off----They are Michellin 8r-19.5 radials---The original oem's were bias tires.

Which should I look for bias or radial-----Also, are 245/70/19.5 the same as 8r/19.5?----Thanks

Hi happyharold4,
Your question may not have a straight forward answer. There is some work for you to do. If the coach came with bias ply tires, the wheels may not be suitable for radial tires. Consider:
1. Weigh (four corners if possible) the coach as it would be for travel (water, food, clothes, etc loaded). If weighing the coach is not possible, determine the gross axle weight rating (GAWR) for both axles.
2. Take the coach to the tire dealer of you choice.
3. Have them determine if the wheels are suitable for radial tires.
4. Let the dealer know the weight each corner is carrying. Or the GAWR of the two axles.
5. Have the dealer recommend the tire that is correct for the wheels and the weight being carried.

Make sure the dealer provides a recommendation that gives the correct spacing between the rear tires. For me, radial tires are the only way to go.

Yes and hope you have had better luck than I finding a tire company that will actually work on 19.5 tires. In the DFW area, I am still looking for someone reputable that doesn't start the 'absolutely not' rhetoric about working on 19.5 tires, let alone selling them.

Michelin, Bridgestone, Goodyear and Hankook all make a 8R19.5, so you don't have to worry about changing sizes.

The comment in the ehow article about wheel (rim) size is a valid one. If you are considering a change in tire size, first check to see what rims you now have. Odds are it is the narrow rim mentioned in the article.
