GEN 2 Toyo RT problems on the Raptor

[Pacific Wheel]

Looking at the pic and the damage on the rim, it looks like there was a significant impact that would have pinched the tire. Toyo and Nitto (same company) are usually pretty stout. However you may have got some from a bad batch.

Lots of people on this forum run Toyo RTs without issues like you experienced, myself included. Not sure if you have a bad batch of tires, but it sure seems like the low PSI and large jolts have something to do with what you are seeing.

Your truck is a mall crawler like most people that run Toyos

The PSI is a non-issue. If anything it gives the tire more flexibility to absorb the impact. Also, load range E has more plys than load range C, so it should be more durable and stout on the sidewall.

Just because he has a mark on the tire doesn’t mean it should have bubbled like that. So unless he hit something going stupid fast or hit something obnoxious, that’s how your tires are suppose to look after going off-road.

So people jump their trucks with 22psi on BFGs?

Flex to absorb the impact... that’s what suspension is for.

Read his post. He said the second time he did not do any jumps.

Have you been off-road? You air down for the tire to make greater contact to the ground and for it have flexibility when hitting objects. That’s why dropping your PSI can greatly smooth out your ride, which is why OP said he was running them at that number. So your wrong, PSI and suspension go hand and hand.

The tire has to be able to flex and absorb the energy as it makes contact. If it doesn’t have any give to it, then the energy of the impact will cause it to break/deform regardless of how many plys that you have. That’s why lower PSI is better while off-road. With that said, there does come a point where too low of a PSI is indeed too low. But 24 PSI is not too low for running fire roads.

C and E are just "ply rating" but not actual plys. Both BFG and Toyo RT use a 3 ply sidewall. Not to say that BFG may or may not have stronger sidewalls but they're both 3 plys. The bubbles can happen to any tire though. I had a customer with a duramax who had his BFG's bubble on a road trip. I think it's more a MFGR defect than a design failure.

From the looks of the damage on the wheel something was hit pretty hard.

Yea, I used poor wording to describe the ply difference. Thanks for pointing that out. Also, thanks for noting the ply side wall. I figured the Toyo had more than 3 plys on the side wall.

Manufacturer defects do indeed happen. LOL that bubble is insane on that KO2. But the KO2 is a better off-road tire all day long when compared to the Toyo RT.

I’m well aware of airing down and how tires function. Slow your roll kid, you have no idea what experiences people here have and who you’re talking down to.

When I ran projects on a lot more hardcore truck than a Raptor we kept them around 35, and that was on a 37” tire.

So yes, most will tell you if you’re pinching the tire against the wheel, your pressure is too low.

Run them at 30 and I’d bet this problem goes away, and the truck doesn’t feel nearly as washy in the corners.

A lot of people like to mod their vehicles and I will admit I do too but when it comes to drivetrain, I prefer to keep it stock for this specific reason. Unless I'm doing a full build or having fun with a junket, modding vehicles throws away the time and money spent of research and development from the factory. The raptor was built and tested with the k02s specifically (if I'm not mistaken, ford asked bfg to make a tire specific to the raptor thus k02 was born) switching tires mean you're not going to get the exact same performance as they do in the factory, for better or worse.
