I have an 09 Nas mfg trailer (not a big fan of it though). I replaced all 6 tires to 205/75/15, but they are rubbing the fenders. The trailer calls for 215/60/15 but they will most likely have to be car tires. I didnt feel comfortable with car tires on a trailer, hence the reason I went with trailer tires. But since they are rubbing, I have to change them. Would you guys feel ok about having car tires on the trailer? They would obviously be the highest load rating tires I could find (94 - ~1500lbs). Do they even make trailer tires this size?

Thanks,
Mike

Are they 3500# axles? How much does the boat weigh!!

Yes they are 3500# axles and the boat weighs 4500 (Magic Sceptor 28)

Always use "ST" rated trailer tires. They're designed to handle the loads and twisting forces when manuevering. (Want to guess how I learned this lessson?....)

Yeah, thats my train of thought also! But in this situation, what can be done. The trailers came from the factory like this, and if I cant find any st rated tires in a size that fits, what can be done?

if you cant find the right trailer tire, run a light truck E rated tire. More expensive and better quality IMO

Also check the sidewall plys. You don't want it to roll of the rim in a hard turn.

Can you raise the fenders? Maybe replace with a different style?
What is the suspension configuration? Can you flip the axle if it's leaf springs? Maybe run a spacer between the axle mounting plate and the trailer frame if it's torsion?

I'd go with an LT truck tire over an ST any day. Myco ships all of their trailers with LT tires installed.

+1 look at the axel and see if the sit in the middle of the spring,,swap to under the springs if they have leaf springs,this will give you about 4 more inches of clearance..if they are tortion you can put a steel block between the frame and the axel mount to raise it..

No I cant raise the fenders (welded to the frame). Its not leaf springs, but I'll have to take a look at the axles to see if there is some adjustment.

In regards to the LT truck tires, do they make them in 215/60/15?
