I have an odd question to ask..
Is there any problem with putting a 15" 205/75 tire and wheel on the front of a set of trailer wheels, ......and a 14" 205/75 tire and wheel on the back of the tandem wheels on a TT. ?
My friend has sidewall damage on one of his 14" tires, and doesn't want to buy another 14" because he was planning on switching over to 15" and increase the load rating.
But this came at a bad time, (money wise) and he can only afford 2 new 15" wheels and tires, at this time..
Can he intermix the 15" and 14" wheels and tires .. for a few months or so, without any problems?
If he did, he would have 15" on the two front trailer axles, and 14" on the two back trailer axles.
Oh, it's a 26' Trail-lite with a GVWR of about 5400 lbs.
Thanks..

I don't see why lot, it will probably lift the front end up about 1" but should not hurt anything. I know the weight police will probably chime in.

A couple months? I would do it and not worry.
I would buy wheels rated 65+ psi and get radials load range D in that size from Maxxis or Denman.

Should be fine. But I'd put the taller tires on the rear axle.
It would be better however if you were able to fine a slightly shorter 15" tire, so they the height would be the same (which will allow the spring equalizer to work) and also ensure you don't run into other clearance issues. A 205/70R15 tire should be same height as you current 14" tires.

Unless the radius of both 14" and 15" tires were identical, I would not suggest doing it. Too many people travel with marginal tires to begin with. Expecting the larger tires, which would have to take most of the weight, to survive is, IMO, WAY too big a risk.
If he can't afford the tires, he can't afford to tow it.

What kind of suspension is on the travel trailer? If it's a leaf-spring suspension with a load-equalizer bracket in between the springs, I don't see a problem (short of it being pretty redneck).
If the axles are independent then the plan fails because putting a larger diameter tire on the front axle will cause that tire to support the bulk of the weight, with very little pressure on the smaller rear tire. It works on the systems with the load-balancer in between the springs because the bracket will pivot and assure than equal weight is on both tires, regardless of the size.

Why not go to the local tire dealers, and find a good used tire to replace the damaged 14" tire, then replace them all when he can afford it?

Does raise a good point. If a replacement tire is going to break the bank, how can he afford to fill the tank ?
