Replacing OEM tires on new wildwood 27dbk

Guys,
I'm new here and I have a question for the group, I am not a fan of the C rated tires that came on my TT so I am looking to replace them with D rated tires. My question is would there be any benefit or negative in going from the stock 205 75R 15 to a 225 75R 15? My thought was the bigger 225 would dissipate heat better, but i'm not sure if sidewall flew would be an issue. Thanks for your help.
Jody

As long as they clear the Frame on tight turns "Tire Lean" and also clear the Top of wheel wells during suspension Travel That is what I would Do! Youroo!!

Welcome from Lancaster PA!!

If they fit and don't find any rubbing going on during travel then go with it.

They do make a 205/75 R15 in a D rating which would be better than your stock C rated..

According to the online charts I looked at the 205/75 R15 LRD is 27.3" diameter, 8.1" wide with a load capacity of 2150 Lbs.

The 225/75 R15 LRD is 28.3" diameter, 8.9" wide with a load capacity of 2540 Lbs.

The 225 will be just a fuzz wider and 1" bigger in diameter. (1/2" in height from axle center) and carry more load.

I'd say if it fits, I see no negative.

All of the above is spot on good advice. So take a look tonight and check in tomorrow. By then this thread should be about 25 pages long and the popcorn will be buttered.

If you do move up to the 225 size an "E" load rating is available, also.

All of the preceding advice is sound. Before making your purchase decision, however, I urge you to double check on the reputation of the tire manufacturer. It is almost impossible to find trailer tires manufactured in the US today. Nearly all come from China, and many of those are poor imitation "knock-offs" of US designs. Do not buy "Mission" Tires, which came on my TT years ago. They were imitations of Good-Year Marathon Trailer tires, and 3 of the 4 failed within 2 years of purchase. Also, be sure to check the tire manufacture date molded into the sidewall of the tires. A reputable, local tire dealer will be ale to provide you with all the pertinent information .

Be sure to check the width of the rims supplied on your trailer.
They may be too narrow to mount the 225's on.
If that is the case, stick with the 205's in a LR D.

Too wide of tires on narrow rims makes for a bad mix. The tire manufactures state the recommended width of rim for each tire size.

I've had great luck replacing the stock "C" tires with a higher rating tire. In my case I was able to find load "E" tires the same size as stock. I bought them at Discount Tire, with the road hazard warranty. I did that specifically because I could pretty easily get to a Discount Tire when traveling if I had a problem. So far, though, so good.

Heat dissipation is definitely better. Last summer I was pulling through west Texas on a warm June day. The pavement was 99-degrees. When I checked tire temperature with my handheld infrared thermometer after about two hours towing on the freeway (at about 70 mph) tire temperature was no warmer than the pavement itself. Made me a believer.

from ALL I have read on these forums the brand Maxxis seems to have the best reputation. They aren't Chinese but made in Thailand I think. They are what we just bought and thus far no troubles

If you are going from a C to E rated tires you have a real good chance that your rims won't be rated for the air pressure of a E most c rims are rated at 65psi max.


Good luck

All above answers are good , but , there are thousands of us out here who have no problems running our OEM tires for thousands of miles with no problems . I never change tires until needed . I tow ten or fifteen thousand miles a year , always checking tire pressure every morning and wear my OEM tires out and then I buy Maxxis .

Thanks guys,
After looking under the TT I didn't feel compfortable going any taller on the tire so I decided on going with a D rated tire on new wheels that can handle the rating. I went with the Carlise Radial Trail HD tire in load D and their grey Highway wheels. I will keep the others for spares.
