Old boat trailer needs new tires. A few questions for a trailer dummie.?

1. Size are 4.80-12. Can I install these myself? If so, do you just use a car hoist?





2. Any name brand places install them for you like a Discount Tire?





3. Should I get just the tires or the tire with the wheel attached?





4. Can you point me to some decent ones at a good price or where to buy them?





It's a 14 foot boat. Any specifics I should know regarding tire weight, etc?|||Just take the trailer to a tyre store, discuss what you need with the tech. and purchase tyres that are rated for the load and the highway speeds you may get up to. The store should fit and balance these for you as part of the cost. Use the best old tyre for the spare.|||Assuming single axle, no brakes.





Got mine at discount tire. If you don't have a spare, get one, otherwise just get the tires. Do let them balance 'em.





Get a bias ply trailer tire, they aren't as cheap as you'd hoped but don't be tempted with a cheaper car tire. Car tires have to withstand horizontal forces from starting and stopping and cornering, but less vertical bouncing because cars have torsion axles instead of leaf springs; your boat trailer tires do a lot of bouncing but don't have to accelerate the vehicle. Unless you're on the tournament trail, the tires will probably fail from UV exposure before the tread wears down (if you keep 'em inflated to 50 lbs).





I just use the car jack and jackstands; cinder blocks work just as well. Put the jack under the axle not the trailer frame else it might not lift it high enough to get the tire off the ground.





If you have another vehicle handy, leave the trailer hitched to the truck, then you don't have to worry about it shifting around %26amp; falling.





This might be a good time to inspect your wheel bearings.
