50 psi tire pressure?

Thanks Les and Jack. OK, so I'll go with the 65 psi on the trailer tires since I bought the D rated Maxxis as well.

Recalling that I'm new to towing, my concern now is whether the existing tires that are on the Tahoe are adequate for towing this size trailer. The tires I have are General Grabber P265/70 R17 6-ply standard load. Thoughts?

I think your good with your exisiting tires for towing your hi-lo, play around with the tire pressures to get the footprint of the tire just right. With my tacoma, I sometimes have more in the bed of the truck on certain camping trips which changes my foot print of my rear tires even with my WDH so I'll put 40psi in my rear tires and 35psi front tires. My tires are Cooper AT3 C-rated LT tire. I did not go with E-rated tires because they would be to rigid for my tacoma truck and make the ride to rough.

Les - just a note about ride comfort. I put the Michelin LT275/65R18 E-rated tires on my truck, replacing Goodyear Silent Armor tires of the same size (which was the OEM size btw). I did it because of the 70,000 mile warranty on the Michelins and after reading several favorable reviews.

I honestly cannot tell they are any "stiffer" at all. To me, the ride is just as comfortable as it was with the older, C-rated tires at 40 psi. But, I can inflate them higher than the 44 psi max that the Goodyears had, and, they have a much higher load carrying capacity. I felt I was running very close to the load limit when towing with the Goodyears.

My truck is a 2005 F150 5.4L 4WD Super Crew, and it has a bed cap on it that I think is about 300#.

I have less than 1000 miles on them, but so far, I'm very pleased.

And, Greg, like Les, I think your current tires are adequate. When towing, don't exceed 65 mph. That's what your trailer tires are rated for, and it will keep your truck tires cooler too.

Maxxis Tires

Jack,
When you switched over to the Maxxis tires, were you able to use the original rims that came with your camper? I am thinking about making the switch as my original Goodyear Marathons, which have worn well, are showing their age.

Thanks,
Jeff

Forgive me but let me interject. When I bought my camper, it had the original 7 year old Goodyear tires on it (I don't recall if they were Marathons). I switched to the Maxxis D-rated and they put them on the original rims.

Hope this helps,

Jeff, when I put 205/75R15 D-rated (OEM size, but higher load limit), I mounted them on the original rims. As I recall, the rim width was 5.5".

But, when I upgraded to the larger 225/75R15 D-rated tires, they needed a 6" wide rim, so I had to upgrade those too. I searched and searched and finally found some 5-lug rims that had a weight rating and pressure rating to match the new tires.

Thanks for the info, Greg and Jack!

Jeff

You're welcome! To clarify, I stayed with the original width tires.

I plan on staying with the same (original) size tires on my camper too, Greg.

Thanks again!
Jeff
