Blown Chinese bomb damage

I had a blowout on 5000 miles Towmax tires; replaced tires on that side with Carlisle. floor foam/insulation in floor above was damaged; groove cut in but not through board above tire. Need to fill and re-waterproof groove (about 1 1/4") inch deep and re-waterproof. What to install or fill the opening with.(appears to be a foam material --white)

You can use "great stuff" spray foam sealant. It expands, filling gaps/holes.

The new tires should go on the same axel.

Unhappy MagooRV

Had exactly same thing with Towmax on our Avalanche 5er. In addition to your damage, we had the fender on that side broken. I but plywood up in the fender well and stapled heavy weight black tarp material to that. We were recently going through all the papers we got with our purchase in 2011 and learned we had tire and wheel insurance coverage: Maybe we are the only one's who don't go through every page of the papers you get at purchase and make a master list of coverages, warranties, etc. but we will now.

Exactly what I was thinking. The previous discussions on this and other forums indicate a blown tire on one side causes an overload condition to the other tire on the same side which will dramatically shorten the life of the other tire, many times causing the other tire to blow. It's not like you have a vehicle with a differential type axle needing matched tires, and at only 5,000 miles, there shouldn't be much wear.

It's a tire warranty thing. Here is a quote - in part - from a trailer tire warranty package.

"It is recommended that all four (4) tires on a trailer be replaced at the same time. However, when only two (2) tires are replaced, the new tires should be installed on the rear axle."

CPE Were these the original tires on your 2011 Montana? Do you recall what year they were manufactured?

Just down the road from you

Also, the new tires are going to be a larger circumference. That would want to make the trailer not track strait with larger tires all on one side.
