superchaser Posted April 19, 2009 Report Share Posted April 19, 2009 Does anyone know what tires I can replace the F78-14's with on my trailer? I'm not sure if I'm allowed to put passenger car radials on there or not. Also if I can use radials, I dont know the load range I would need. The trailer is a 1984 Magic single axle and the boat is a 19.5 ft bayliner bowrider with a 125hp engine. Im not sure of the weight. Any suggestions? Thanks Dave Link to comment Share on other sites More sharing options...

RuNnYoOzE Posted April 19, 2009 Report Share Posted April 19, 2009 http://bayliner.boats.com/boats/search/boa...yliner+bowrider here is a webpage where you may find a boat similar to yours ( don't know the year?) it has various boats and a search engine with specs on weight Link to comment Share on other sites More sharing options...
superchaser Posted April 19, 2009 Author Report Share Posted April 19, 2009 Thanks again for the great info. Net weight of boat is 1995lbs. I'm guessing 300lbs for engine. Now, to find some tires... Cheers Link to comment Share on other sites More sharing options...

lew Posted April 19, 2009 Report Share Posted April 19, 2009 I'd shop around ..may find some reconditioned or used .. When your towing a big heavy boat at hiway speeds your trailer tires are one of the most important things you've got going for you and I don't think buying used or reconditioned is a good idea. The price of a set of good trailer specific tires is pretty cheap compared to the total cost of whatever rig your towing. Just my 10¢ though Link to comment Share on other sites More sharing options...
Marc Thorpe Posted April 19, 2009 Report Share Posted April 19, 2009 I agree with Lew,dont skimp on the rubber Good wheels can be a life saver Link to comment Share on other sites More sharing options...
Fisherman Posted April 19, 2009 Report Share Posted April 19, 2009 I had the same size on my travel trailer, it works out to a 205/75/14 Load range C. You can go one size larger to a 215/75/14 Load range C, they have a a bit more margin of weight capacity for a few dollars more. Link to comment Share on other sites More sharing options...
DanD Posted April 19, 2009 Report Share Posted April 19, 2009 As Lew said don’t screw around with used tires or put a passenger vehicle tire on this trailer. Make sure you have at least a 25% margin from the maximum weight rating of whatever tire you decide on. Also check the date code on the tire; as to when it was made. Anything older then 2 years, I wouldn’t accept; even if, it had never seen the road. Rubber never stops curing and they become hard and porous. Once moisture gets to the steel cords; they begin to degrade and what else holds a tire together? All tires have a ply & date code stamping; the last three or four digits are the date. The middle two digits are the week, the last two are the year; they were made. The tire above was made on the 8th week of 2006. If a tire was made before 2000 it’ll only have three digits. Ie. 235, this tire would have been made on the 23rd week of 1995. The MTO is seriously thinking (no one will make a stand) of initiating a “best before” date of six years old and then the tire must come off the road. It would also be illegal to sell and install a tire of six year of age; regardless whether it was new “looking” and never used. Dan. Link to comment Share on other sites More sharing options...
Tybo Posted April 19, 2009 Report Share Posted April 19, 2009 I always go the most ply the wallet allows. This is not for weight.But for temperature. I like to call it super cruise. The fastest I can go,With the best fuel. When over rating your tires,You must adjust your pressures. Or you will get tread roll. Link to comment Share on other sites More sharing options...

superchaser Posted April 20, 2009 Author Report Share Posted April 20, 2009 I went to crappy tire yesterday looking for tires. I told the manager what I was doing and he said it was illegal to put passenger car tires on a trailer. I dont know whether to believe him or not. He also said when importing a trailer from another country (ie. US) trailer only tires must be installed to pass inspection. If I get a chance today I will contact MTO to verify.

Tybo Posted April 20, 2009 Report Share Posted April 20, 2009 Tread Roll occurs when the tire gets to hot. The rubber becomes softer and then the tread is push over. You will know when this is happening, When you look at the tread and their is high spots on one side, Or a high ridge. Link to comment Share on other sites More sharing options...
Fisherman Posted April 20, 2009 Report Share Posted April 20, 2009 Hm..learn something new every day, heat does a lot of damage to tires, didn't think it would get that bad. Link to comment Share on other sites More sharing options...
