When upgrading your 4.80x12 tires to The Taskmaster 5.30R12 Radial Trailer Tire # TT53012C tires you can use the same 12 inch diameter by 4 inch wide rim. You will just need to make sure the larger tire fits.

This radial tire is great for highway use. It is constructed with double steel belts and double polyester cords. The tire has a load range C with a 6 play rating and has a maximum load of 1,050 pounds at 80 psi. The tire has a maximum speed rating up to 81 mph.

I attached a review video link below.

Hi, I'd like to buy radials, instead of bias ply tires, to replace the current 4.8x12 Carlisle Sport Trail LH tires on my 2004 Coachman Clipper Sport pop-up. With the current tires on, I got under it the other day and found that I have 1.5 inches of clearance from the inside sidewall of the tire, and I have about 2.5 inches of clearance from the top of the tire and all around. Do you have a recommendation? I'm a bit concerned about whether I can safely move into a larger tire size. Brian

@Brian You're pretty tightskys on clearance as it stands now. I wouldn't recommend going with a larger tire. If you haven't had any problems with your tire rubbing at this point, we do offer a 4.80-12 radial tire in a load range C as part # TA98RR that would work for you.

Thanks for the recommendation Mike. It looks to run at 90 PSI, should I be using a high pressure valve and can you recommend one that works with that taskmaster 4.8x12 tire?

@Brian You would indeed need a high pressure valve stem. 12 inch rims have a valve stem hole diameter of .453 of an inch, so you'll want to use # AM20906 which is rated for up to 100 psi and includes a .453 and a .625 grommet for the valve stem hole which will work perfectly. Hope that helps!

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

An ST205/75R15 will fit on rim widths measuring 5, 5-1/2, 6, or 6-1/2 inches. For that tire size already mounted on a steel wheel with a 5 on 5 bolt pattern take a look at #AM32409. I have also included a link to all of the wheels and tire/wheel…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…
