Swap from St tires to LT

I dont want to start another LT vs ST debate. I just wanted to show how i did the swap on my trailer.
I used lift block designed and machined for trailer axles with larger u-bolts to lift the axles 2 inches. Then i swapped the 14in wheels with 205/75R14 tires to 15in wheels with LT235/75R15 tires. These are the smallest LT tires i could find. I have put about 1000-1500 miles on it so far and i have not noticed any difference in how it pulls or rides. But i like the extra 800lb capacity thee tires provide and the higher speed rating. I also added a BAL tire carrier so i wouldn't damage the rear bumper.
My X-chocks still fit between the tires perfectly and i have zero clearance issues anywhere.



  • Nice job Chuck and a worthwhile mod, tnx for taking the time to post the pics.
  • I used 2in blocks because these tires are 3 inches overall bigger than the stockers and i already had a few marks where the factory tires rubbed above them.
    Also i got the blocks and U-bolt from
    http://www.trailerblocks.com/
    A little pricey but great quality!
  • Was 2" lift necessary or did you just want the additional ground clearance?
  • Good job.
    Where did you get the lift blocks? I am using solid steel custom made ones, just because I couldn't find any.
    It appears that you could fit 16s if you wanted to... Would need new drums and rims though.
  • Good job, I put that same spare tire carrier on my 5er & love it. :)
