LT225/75R16 on a 2011 Jayco33rlds
I posted in another thread my concerns with the ST225/75R15 Goodyear® Marathon Radial on our 2011 Jayco33rlds. I received a lot of good information on different ST tires and some suggestions on upgrad...

Do you have 6 lug drums? If so, then that is a great start as 16" rims are most common with 6 lugs. If not, then a swap to 6 lug drums is likely the best solution.
With a diameter difference of only 1", that will only change this measurement by 1/2" over what you have now. So you are probably OK here, though you do need to check it to make sure. If you will not have the necessary clearance, then it can be obtained by a small lift. If the springs are over the axles, then a 1/2" lift block will work.
The other clearance issue is the space between the tires. You need 1" when level. So you will need 2" now in order for the new tires to work. You likely do have this much space. If not, then there is no easy way to solve this issue
Yes, currently have 15" x 6" Rim - 6 lug on 5-1/2.
I'll need to re-check but feel like I have at least 4 inches from the top of the 15 in tire to the inside of the wheel well. . I know I have more than two inches between tires. Where did you get your clearance info?
The clearance info is straight from the Dexter manual.
Just checked. I have 2 1/2 inches clearance from the top of the 15 in tire to the inside of the wheel well and 5 1/2 inches clearance between tires. Doesn't appear like this is going to work without the lift kit you mentioned. I plan to call Jayco Monday to verify. I'll probably end up going the most conservative direction and mount five Maxxis M8008 225/75R15 10ply ST Trailer tires with the expectation I'll need to do it again in about 5 years. Thanks!
If so, then you already have a clearance issue. It is possible that you just haven't hit a bump hard enough for the tire to contact the wheelwell,,,,,,yet.
More likely is the measurement wasn't done right.
The axles are constantly moving and shifting in relation to one another. If the equalizer between the springs is not level, then one tire will have more clearance than the other. A simple way to account for this is to measure the clearance od both tires and divide by two.
And... ST tires are considered used up at 3 years.
From Discount Tire:
Time
•Time and the elements weaken a trailer tire.
•In approximately three years, roughly one-third of the tire's strength is gone.
•Three to five years is the projected life of a normal trailer tire.
•It is suggested that trailer tires be replaced after three to four years of service regardless of tread depth or tire appearance.
