245/70 Sailuns

There was a thread earlier where someone was thinking of using 245/70-17.5 on the coach. Im researching possibly the same idea.

Did you do it ? And how did it turn out ?

They would need to go on a 6.75"~ 7.5" wide wheel , you should make sure your wheel is with in this spec. My current Sailun tires are 215 wide and leave fairly deep ruts in the grass , my thoughts are a bigger foot print would help reduce the ruts. They would also be slightly taller and wider and could be run at a reduced air pressure because they are 6000 lb rated tires. It seams like they are in short supply right now!

That was my basis for starting to look, Mark. We are in softer surfaces at times, like right now in Myrtle Beach in a-sandy site where one side is about 4” deep in soft sand. I’d like a bigger and wider footprint. Looking for wheels now. I’ve also got the 215 Sailuns

Spent some time the other night talking to a good friend who is a retired Goodyear truck tire engineer about my idea of going bigger and then running less pressure but still higher than minimum needed for the weight on the load chart. He said no reason not too, that is why they do load charts. Doing that with the 245, I can run 80 psi and still be at 4800 lbs per tire Ride and handling should be much better, especially with the IS.

We are heading to Carolina pines in SC in late May , its my wifes birthday and she wanted to go someplace warm.

I think if you have a wheel that is wide enough this is a win ,win. I think dropping the tire pressure to 90 psi would be a big improvement but as you stated with IS not sure how much you will notice in the truck. I have a Hensley air ride BD5 hitch and that has done a good job of isolating the truck and trailer when going over bridges.

Simple tire . com has been my go to for Sailun tires. I would see if a local shop can ballance them , mounting 1/2 size wheels are easy they don't have bead locks so the tires fall on the wheels.

Found 6.75” wheels on etrailer and Tredit, looking a bit more as I’d prefer to have 7-7.5”. In any case, next year when I need to replace the 215’s, I’m going to go to the 245.

Figure a hot shotter or equipment mover will jump at a mounted set of H Sailuns even if 5-6 years old. That will help offset the upgrade some. Lol

I got a set of Alcoa wheels , They where modified by Rickson wheels . I dont know what he does to them and it took 4 months to get them from him. If you have the time give Alcoa a call and see what the differance from the wheels that use 9/16" cone style lug nuts and the 5/8" washer lugs . As far as I know all the Redwoods used 9/16" cone lugs.

The more I think about it he countersinks the holes for taper seat lugs
