    Toss the Westlakes?

    To make my question even more inane , I’m actually a 40+ year master tech. So - when we got the Reflection I replaced the E Westlakes as soon as I towed it home. Solitude has G’s which seem to have a better rep. Have 8000 miles so far , balanced them first thing , and run TPMS. They look fine with no noticeable wear , but we have two 2500-3000 mile trips coming up in late July (read really hot ) and October.
    So what do you folks think in my informal poll?
    Thanks , Charlie

    I have G rated Westlakes on my Solitude. The hold air and don't leak down while sitting. They are round and do not wobble. They have no discernible wear on them after a few thousand miles. I have used them up and down long Arizona grades in >105* heat with no issues.

    Yeah...I'd listen to the Internet and replace them.

    So far the G rated Westlake tires have a good reputation. The E rated Westlakes on heavier 5th wheels? Not so much. Lots of threads on the subject.

    IMO, the decision to replace E rated Westlake tires on heavier 5th wheels boils down to how much risk a person is comfortable taking. If you'd rather not spend the money to replace your factory E rated tires and don't really mind getting flats, keep the Westlakes. If the last thing you want to do while towing a huge 5th wheel is change a shredded tire on the side of a busy freeway in the rain, replace your tires. I fall into the latter category.

    Even though the G rated Westlake tires seem to be holding up really well, they were too new for me to trust based on the history of their E rated tires so I replaced them with Sailun S637 which have an excellent reputation. If the G rated Westlakes would have had a longer history in the RV world, I would likely have kept them. As it is, I have no regrets. The Sailuns only cost me $344 net after selling the Westlakes. A minor expense in the scheme of things.

    The OP has a 310GK-R. They came with G rated Westlakes as he indicated in his post.

    Yeah, I know. I kind of drifted off topic a bit. That happens to me when folks mention Westlake tires. Sorry.

    My personal opinion is that there are a lot of people that haven’t said much because they haven’t had an issue. Those that do, tend to speak up. Those that haven’t, not so much. I don’t plan to let the opinions of the few that have had issues influence mine. My trailer (less than 12,000# GVWR) isn’t too heavy for my E-rated tires (3,520# each), so I’m not too concerned at this point.

    Along the same line, I’d be interested in knowing the actual percentage of failures for the Westlake tires compared to others of a similar size and rating.

    I'm also a certified Medium/Heavy Duty Master Tech and have been both a wrench bender and in management of fleet maintenance for over 40 years to include military, public transit, and now school district fleets. Our Momentum has the Westlake G's. So far I have no complaints with the tires. Granted I only have about 3k miles on them, but they have been over some of the worst roads out hear in the desert southwest (I40 between Flagstaff and Kingman, and I15 between Vegas and LA). Last weekend we came home from San Diego across the Mojave Desert in 105+ weather without issue. My TPMS recorded tire temps just shy of 130 degrees, and the pressure increased from 110 to about 124 PSI. I most definitely kept an eye on them but felt confident they would be okay. I did check them at every fuel and potty break and they seemed fine. At this point, I'll probably run them for another season or two, then change them out. To what is undecided at this point. On a side note, I've had many trailers over the years (boat, ATV trailer, RV's) with a good cross section of tire brands. Some lasted longer than others, but here in the Desert Southwest, 3 years on a set of tires seems to be the sweet spot. Any longer than that and you're gambling...

    I am upgrading the LR G Westlakes on my Solitude to Sailuns just for peace of mind. On initial inspection (and I am no expert) the construction between the 2 seems pretty similar, similar bead thickness, sidewall thickness, weight, both are all steel construction, etc.

    I plan to sell the Westlakes which should make the "peace of mind" less expensive

    Can't give you percentages, but one of the original Westlakes on our rig had to be replaced at 2 months because it kept going flat (couldn't figure out why). Then a second one developed a major bubble on the inside sidewall after about 1,000 miles. Since we had a major (10,000 mile) trip upcoming, we replace all of them at that time with the Goodyear Endurance tires. 10,000+ miles later, they were just checked for our summer trips, and they are holding just great, lots of tread and no cracks.

    I'm leaving them on my momentum.

    No issues so far this last year. I have G rated tires though and I wouldn't have ordered a heavy coach with E rated.
