Can Lowes 4 by 6 Trailer Have Speed Rating Increased
Updated 02/03/2026 | Published 07/30/2024
Question:
I just purchased a 4x6 Carry-on from Lowe’s and it came with 4.80-12 tire/wheels. The hub pattern should be 5x4.5 and I would like to move up to 15 wheels. I’ll never pull/load the trailer to its 2k-ish rating, but I would like to be able to go faster than 60 on the freeway, as I plan on taking 6hr drives every couple of weeks for the next few months. I will mod the trailer fenders and flip the axle to accommodate the larger wheels/tires, but I am unsure of how wide I can go before I run short of space between the tire and frame. My assumption is that most people have done this before, but I would like to be confident I don’t make unnecessary purchases, and have to deal with returns or eating unnecessary costs. https://www.lowes.com/pd/Carry-On-Trailer-4-ft-x-6-ft-Wire-Mesh-Utility-Trailer-with-Ramp-Gate/3013702

Hey Weedy, I actually have a much easier solution for you since you basically just want to increase the speed rating of the tires. Instead I would go with the part # TT48012C which is the same size as you have now but is rated for 81 mph. This will save you a lot of headache and time.

Hey Weedy, how did things go with the Taskmaster 4.80R12 tires on your Carry-On trailer? Did the higher speed rating make your long freeway drives smoother? Your update could make it easier for others looking to upgrade their trailer tires for similar trips.
