Thread: Westlake tires?

The Goodyear Endurance does NOT come in a G rated tire. However, the Goodyear G614 comes in LT235/75R16 which is a load range G tire. It is rather unique in that it has a truck tire construction and designation, but was designed specifically for towable products. It is also made in the USA. Many owners of larger fifth wheels have run on this tire with outstanding results. Its load index is 126, meaning it's rated for 3,748 pounds. It is speed rated "L", which is 75mph.

We have Westlake G rated tires on our 2018 Solitude 310 GK and have been to from California to Minnesota twice as well as many 500-1,000 mile trips. We've had no issues with the Westlake tires. The Goodyear endurance does not come in a G rated as far as I can see. I've been told that Goodyear does make a G rated trailer tire for heavier 5th wheels, but can't seem to find it. Any help out there would be appreciated.

Does anyone else find it interesting that on the Lions Head web site, they don't even list the 235/80R16 G-rated tires that are being put on the new Momentums in their spec sheet? I purchased a 2020 349m which came with these tires and while trying to verify specifications, I noticed it wasn't even listed:

Shows the ST235/85R16 G but nothing for ST235/80R16 G
I installed Goodyear G614s on my last trailer and loved them but they are over $300 each right now. With the Sailun S637T ST235/85R16 G (5540993) available from Amazon right now for $115 each plus tax and a 4400lb load rating, it's a steal.
When you search for that Westlake size (80 and G) and follow the links, you generally end up with an E-rated tire, or an 85 size. Perhaps they are just slow getting them into the pipeline?

One of my Westlake 10 plys developed a split in the sidewall within the first week of ownership. I promptly replaced all 4 tires with Sailun 637 ST's. I have now towed over 12k miles with zero issues. These tires do ride rougher due to their 14 ply construction. With a 4400 lb load rating, they're way overkill for my 12k GVW trailer, but then again so is my truck. I like having a large safety margin.

I can somewhat agree but the unless one was overloaded the e-rated tires should have had enough capacity. G's are overkill (not that that is a bad thing) But the e's should have held up. I believe they are rated at 3520 per tire which is higher than the axle rating by a smidge. Close to the limit but still under. Even with only 20% on the pin your only at 6600 per axle at max GVWR
I just replaced my G westlakes with the G Sailuns. Same size tires but the Sailuns have a higher load index. I run them at 95psi cold which is still good for almost 4000lbs (almost the same as the westlakes at 110psi).
My Dad's Pinnacle has 255/85 e rated endurance tires which carry a 4080lbs rating at 80 psi. The larger tire allows for more air volume at 80 psi which is ultimately determines maximum weight ratings. The more air a tire can hold the higher allowed weight rating.
I do like have the thicker/heavier side wall though for the abuse trailer tires take on curbs and sharp turns.2021 Solitude 375 RES-R

I just purchased a 297rsts travel trailer. I am still unaware of all the issues with the Westlake Tires. My dealership denies they have had any issues, but they have only been in business representing Grand Design one year. Should I be concerned? Should I worry about what grade the tire is for the travel trailer? There seems to be some issue with putting the wrong grade tires on certain rvs? I am very concerned, but the dealer says that we are paranoid and to stop reading all the posts on the internet. They think people are purposely trying to scare others. I told them these people own Grand Design products and are happy with them but do have issues that get posted. I am very concerned with the dealers attitude, but it is the only one within 2 hours of us. Any comments?
