Time for Heavy Toy Hauler tires...how about these?y

[DHayden]

Pulled them all off and headed for the auto shop today. You can definitely see the weight/quality over the OEMs. I had to lube those babies up good to get them on the rim!
I went ahead and put the liquid balance in them that I had bought and never used for my truck. We will see how that works out. Was going to have a shop put them on but with the hassle and the cost of the shops, I just did it myself. $27.50 for an hour on the tire machine and disposal fee for 6 tires. Went ahead and filled them to 95psi

They are definitely a great tire. They will go on my new dump trailer, probably sooner than later judging by the amount of flex in the factory tires sidewalls when loaded and how warm they get.

I only have 15" tires on my little 30' toy hauler and ended up with Mastertrack E rated. They also make a F rated version in 15" with all steel belts and the 16" versions are all steel belted too. I've seen a few of this brand around, two years old and they aren't weather cracking like my other Chinese Trailstar and Towmax tires did at the same age. Read a few reviews with positive comments on RV sites from 2012, 2016 and 2020. So far so good, around 2,000 miles now running 65 to 70 mph in 90 degree weather. Tires are rated for 75 mph... so they claim.

I would look at how the LRG's are constructed. If it changes the sidewall construction to go to a LRG tire then you may not be able to reduce the pressure as much without potential issues as well. It also might not be an issue for the load you

When I ran 19.5's on my 05 the sidewall construction on those tires didn't allow for pressures to be reduced below 70 psi, regardless of the load. It was more pressure than I wanted to run a lot of the time.

carry.

Was that the issue when you had the 19.5's? Do they mfg state a "min" pressure? I was looking at the Sailun S637 235/80/16 which is rated at 4080@110psi (LRG) versus the current tire I am running 235/85/16 which is rated at 3940@95psi (LRF) so other than running at the higher pressure, I only gain 200# / axle. My only real concern is my AL wheels are stamped "110 PSI" so is it safe to run with tires inflated to 110 PSI cold? I will try to investigate the sidewall construction differences, but I was hoping the more commercial tread pattern on the Sailuns would give me lower rolling resistance and less side wall flex (lower temps?), the current tires I have twist and flex quite alot when turning, less that the OE tires did, but still alot, I plan to weigh it this next weekend time permitting, but running low on time before leaving at the end of June.

Manufacturer stated min pressure. The published min pressure was 80 psi, but I got an email from them saying I could go down to 70.

The high min pressure was not unique just to the 19.5’s I had, but rather all 19.5’s I researched. The pressure is required to keep the bead seated, as the wheels are not designed like whole number wheels.

I have not talked to Sailun about my 19.5s but the chart I found started at 65psi. I ran my rears (duals) at 50psi for a while with no issue but bumped them up to 65psi when I found the chart.
