TV Rear Tires

I run my rear TV tires at max rating when towing our 5er. :)

Just curious what everyone else does with their rear TV tires when towing? Do you bring the inflation up to tire max or keep at recommended level for vehicle?

I bring mine up clse to maximum so that the additional load is within spec for the tires. What I have found is that I don't bother to let the air back out when no longer towing so now I have harder pressures at rear than at front. But the truck does better on mileage and it feels no different.

On my F150 when towing I ran max of 44psi when I had P's on it. Switched to E's and ran 50psi. Non towing I ran the door sticker IIRC was 34-35psi.

On my 3/4 ton I run the door sticker for non towing. 65f-45r. Towing I run 75f 80r. Depending on frequency of towing I sometimes leave the towing psi in. If I'm going every other weekend I leave the towing psi in. Anything longer than two weeks between trips I air down. I'm retired so my driving is way less than a working guy so I don't put more than 100-150 miles on the truck between camping trips.

On my half ton I went to about 50PSI F/R in LT tires. On my 3/4 ton, I run 10psi over MFR recommendations all summer, so 60psi front and 70psi rear. I run at MFR recommendations in the winter.

I leave mine at 65 or 70 all the time. Front stays at 80. Michelin ltx ms-2. 20 k on them like that and all looks fine.

I air my tires up the day before I hook on to the fiver. I usually run 75 lbs. in the rear, and 70 up front. I had steel valves installed on the inner rear wheels. Makes adding air a breeze. Best 40 bucks I have ever spent. I do take a small air compressor with me. Just in case I need to add air to the RV tires or Trail Air system on my fiver.
