15/20psi on pavement - How long?

2019 OR DCSB with stock Goodyear Wranglers and wheels.

I'm starting to air-down to get through seasonally-muddy access roads. Sometimes, though, I need to drive about 5 miles on pavement, about 40/45mph, to the next road.

How long can I get away with my tires at 15/20psi on pavement at about 40/45mph?

I'm ok putting wear on them since I need to get better tires anyway. I'm worried about damaging the sidewall and blowouts.

I've searched the forum and googled this, but I can only find very broad recommendations, nothing that addresses such a short drive.

 

Just stay under like 45 and you’ll be fine. Don’t try to make any aggressive turns at speed.

 

Thanks. Yeah, I get the handling issue. Fortunately I upgraded the shocks and swaybar, so it's not as bad as it could be.

 

Google "tire deflection and heat"...
The stock Goodyear sidewall is very thin; to me, it felt like penny-nickel thick.

I'd slow it down, if possible.

 

I do a lot of perch fishing on the beach and have to air down to 12-15 psi to get to some of the spots I like to go. In order to jump between spots on the beach, I have to drive on paved roads, so I know what you mean about not wanting to air back up. Like other folks suggested, take it slow and don’t roll a bead off your rims.

I’d strongly suggest investing in a Viair portable air compressor. I have the 88p air compressor and it works well for what I need it for, although it is somewhat slow. Maybe look at the next tier up for a higher CFM rate.

 

Ive done this before on several occasions. Hop out every once in a while and put your hand on the tire to see if its getting hot. It's the heat that causes the tire to fail and blowout. This will give you a good gauge to know if youre pushing them too hard aired down

 

I'm debating a Viair 400 something with auto-shutoff, vs. a "flat-inflator" device like a DeWalt (which I already have). This pavement thing is part of the equation. If I can get around and just air back up when I'm done, then the DeWalt is better because I can set for each tire, put equipment away, and it doesn't matter that it's 4/5 minutes. But if I'm airing up/down just to get around, then yeah, the Viair, because of the speed.

 

Good idea.

 

Exactly 4.8954 miles.

 

Depending on the Max load rating on your tires and the actual weight of your truck you should be fine . Just watch your speed

 

I aired down for the first time the other day, and don't have a compressor but knew there was one nearby. Just a handful of miles down the paved road. Made some turns, drove at 40mph max and was at around 13 PSI. Truck felt fine, soft and harder to move the tires, but drove carefully without issue. Excited to get a compressor
