Question:

Utility Trailer / Tandem Axle?

I just bought a used 6‘x12‘ utility trailer with double axle.the trailer is in great shape and has all new wood slats installed.BUT.I noticed that the tires on the rear axle are a little large than the front.I think they are 235‘s on the rear and 215‘s on the front.This is my first tandem axle trailer.is this standard or should all tires be of the same size? It would seem with the rear axle tires being larger that most of the weight being hauled would be put on the rear.if someone has any info, I would appreciate itall the tires are nice, great tread, no sign of wear.

Answer:

Yes its an issue. Never mismatch sizes on the drive axle, it can cause axleshaft or cv shaft breakages. If you can't afford same size tires at the moment, put the same size tires on the same axle until you can get matched tires all around. Unless your car is AWD, then you need the same size now, or you can break drivelines or the transfer case.
ok, 1st, take a axel mesurement from hub to hub, additionally what hub bolt trend length is. Have the leaf spring U-bolt length and length additionally written down. The axel leaf spring mounts come loose or welded in place. i stumble on its much less complicated to weld the mounts myself. 2d, check out the leaf springs for placed on. third, A wiring kit, now which you are going to have electric powered brakes on the trailer, will might desire to incorporate wiring to pass from axel to trailer plug, one million break away change, one million back up battery p.c for break away change, one million 7 way plug for trailer. 4th, The checklist in hand pass to Dexter axel information superhighway web page, and fill in the blanks. put in quite few axels in my day, completed axel flips on trip trailers and Dexter axels are the right.
it depends on what you are planning on using the trailer for, and how much weight you will be putting on the trailer, and if it is a five lug axle, or a six which is more heavy duty for more wieght. also the distance you will be traveling makes a difference. a lot of people use car tires, they are stronger than the tires on the trailer when it came from the factory. and unless you plan to tow heavy across the country it should not be much of a problem.
Bend down and take a look (from the side) BETWEEN the tires, where the two springs connect to a swivel device. The suspension can handle a small difference in tire size as long as this swivel is not in a bind. The suspension adjusts itself so that one axle is NOT carrying more weight than the other (normally). The design of the suspension on tandem axle trailers is quite ingenious. It also compensates for conditions where the trailer is not level while moving.
NEVER, EVER mix tire sizes or even different brands. This can cause dangerous handling characteristics, not safe. It can't possibly drive straight? Overinflating by 10psi is not smart either. Dangerous car, get it off the road NOW!
