We recently purchased a Coachmen Catalina 243 RBS. The PDI went went smooth. Only 1-2 minor items to correct. However, after reading the FR forums, it appears the FR installs China Bomb tires on all units. If so, how do I identify a China Bomb tire, and what recourse do we have with the dealer or FR?

Welcome to the blown tire club. Here are some quick personal opinions and recommendations. First, almost all trailer tires (designated by the "ST" before the size) are from Asia, usually China. That doesn't mean they are all the same quality. Good Year Marathon tires have a 6-year warranty, and are backed by its dealer network. Having said this, in my opinion the best way to attempt to avoid costly damage is to install an aftermarket tire pressure monitoring system, or TPMS. The one we use is the TST 507RV that we purchased online from Vulcan Tire for $229. It will show tire pressure and temperature, both of which should indicate a problem prior to failure (low pressure or high temp). Don't forget that if you add such an aftermarket system that the sensor adds weight at the valve stem (this model = about 0.9 ounces). So have your tires rebalanced, or add the equivalent weight opposite the valve. Hope this helps, and wishing all safe travels.

Turned out good for me. Thanks again Gary!

XPS Rib | Michelin Tires
Looks like a nice tire. You will likely be replacing the rims as well, right? According to the info I found on the 2010 Wildcat 28RKBS, it comes with ST235/80R 16/D tires, with 65 PSI tire pressure. If this is correct, then there are likely two issues with those rims and the Michelin XPS Rib LT245/75R 16/E tire. First, the minimum rim width required for the LT245/75R 16/E tire is 6.5", and your existing rims are likely less than this width. Second, and most important, the rims are likely designed for "D" tires at 65 PSI, not "E" tires at 80 PSI. The rims should be marked on the inside (where it mates with the hub) with its maximum weight. Just FYI based on a lot of research and upgrading our 5th's tires (and rims).

Costs of tires etc

Do we have a cost for these tires, or is an alternative a wireless tire monitoring system?

Actually three issues. Don't forget that rubber valve stems have a maximum air pressure rating (or they can blow out of the rim). Typically rubber valve stems have a maximum pressure limit of 65 PSI. Therefore 80 PSI valve stems (or greater) are typically screw mount metal types.

"ST" tire load capacity

So in summary, how does one determine the correct "ST" tire?

First, look at the axle weight rating on the RV placard. Let's say each axle is rated for 6,000 lbs. That's 3,000 lbs. per tire. If you research "ST" tires, you'll find that their load rating is a static measure - not like "LT" and "P" tires that take into account other dynamic forces (steering, power, traction, etc.). So the rule of thumb is to take the maximum static load and increase it by approximately 15% (or an increase of one load rating) for an "ST" tire. So for a 6,000 lbs. axle, at 3,000 lbs. per wheel, it should have an "ST" tire rated at 3,000 + 15%, or a rating of 3,450 lbs. An ST235/80R 16/D tire is rated at 3,000 lbs - that's not enough to carry a 3,000 lbs. live (dynamic) load without the risk of failure. The appropriate "ST" tire would require a ST235/80R 16/E rated tire, with a load rating of 3,420 lbs. Note it's the same size tire, but an increased load rating from "D" to "E".

I would like to think this helps to explain why there are as many "ST" tire failures - not only because of "cheap" tires, but because the industry has placed tires that are at, or past their dynamic load limits. Also it is interesting to note that the new 2015 Wildcats come with "E" rated "ST" tires that are one load level higher than the actual rated axle weight. However, for older units, none of this changes the need to insure that the rims and valve stems are rated for the increased load rating, should one decide to move to a higher load rated tire.

My 2010 Wildcat came with ST 235/80R-16 rated at 3500lbs @ 80psi E tires with wide mag style rims which should fill all the requirements for the Michelin Tires. I will have the rim width checked and confirmed prior to buying these tires.

But glad you brought it up for those who's rims won't work with these tires.
