Looking for Information on Westlake super st. 205-75-R-15

[ranger tim]

I am looking for information ONLY on the West Lake Super ST 205-75-R-15 Speed rated D and load Range D tire from anyone that has had a problem with them on their travel trailer. I know other people have had problems with West Lake tires in others sizes and other trailers and weights. But I would like to hear from you with same size trailers. I do keep trailer under a covered carport when not being used , check tires before any trips and I also use a tire monitoring system. I have a 2019 Grand Design Imagine 2600RB. Thanks Tim

We have a 2020 Imagine 2600RB on Westlake Super ST 225/75R15 tires. These are factory with over 4500 miles on them with no issues. They are rated as range E tires. I measured the spare tread against the on ground tires and they show about 15% wear. When parked on the driveway, I cover the tires on the sun side to slow down environmental damage. We also run with TireMinder TPMS on the axle and spare tire. Pressure is 80psi.

Next week we will have the entire rig (2020 F-250 + 2600R weighed by Safe Weight. You get weighed as you would normally travel (1/2-3/4 tank fresh water, drained grey/black, bikes on rack, food, clothing, etc in trailer, normal load in truck (full fuel, driver+passenger, 2 dogs, and what we normally travel with in bed). They weigh each wheel to get truck weight, trailer weight, and GCVW. They also measure height and give you side to side weight (balance) and best tire pressure for vehicle and trailer weight. I really think this is better than CAT Scale which only provide axle and total weights. The side to side should help with handling and balance of the trailer.

Only have 1300 km on mine because trailer is brand new but zero issues and I don’t expect any

They are a great tire and I have no plans to change them until it is time

The issues were with larger units and a completely different tire than we have

It probably has more to do with the weight of the trailer. My ‘21 23BHE has the 205/75/R14 on it.

Something you might want to check. I might be wrong, but the year may have had 3500LB axles. The 2020 came with 4400LB axles. Changing to load range E may not accomplish exactly what you are looking for. The lowest rating (tires, axles) is the maximum load recommended.

Thanks for the info. I am going to check with my dealer and see what they have to say on axles and tires.

If your salesman cannot give you the answer quickly, you need to crawl under the same model trailer and read the label on one of the axles. Both will be the same rating. Keep in mind upgrading tires will not change GVWR.

Looks like Grand Design put some 2600rb with 3500 axles and some with 4400 axles. I have the 3500 # axle on my 2019 trailer and the 205-75-R15 tire, the dealer also said it a good idea to change tires every 3-4 years .They also had a recall on some of the 3500# axles but mine was not one of them.

My understanding is they went to heavier axles for 2020. As for replacing tires, if you maintain them, protect them from the sun when parked, they will last longer. But you do have to keep an eye out for cracking, keep them dry and off the ground if possible when in storage. We have TPMS on all (including spare) tires to keep an eye on pressure. I check pressure each morning (by gauge) before we hit the road.

And I make sure to put covers on the side parked towards the sun (our driveway is north/south) whenever it's parked there. I also rotate front to back (same side) at least once a season. And all 5 tires (including spare) are balanced. This trailer has over 4K on it. The previous two trailers each had over 15K on them and tires were replaced at about 11K. The first was because we didn't cover the tires in storage (northern AZ). The second was upgraded to GY Endurance because I had one tire badly worn when a bearing went bad (the tread held on but the wobble just ate it up).

And you might see if you can get the dealer to replace the tires with GY Endurance as part of the deal.

Just like the rest of the rig (and your TV), maintain it and you will get the best life and service out of your tires.

I changed mine immediately when we got our 2021 2500RL to Goodyear Endurance
Why risk it. If one blows can cause extensive damage greater than the $650 to change them
Peace of mind, why worry.

Compare them yourself in person not inflated.
The side wall of the Westlake is inferior to touch and sight

Either way get a tire monitoring system

We had no problems with our ST205/75R15 LRD Westlakes through about 3,600 miles. We are running Goodyear Endurance now after uneven wear of the Westlakes that resulted from bent spindles.
