Big guy, new bike, need tire help.

I'm 6'9" 265lbs. This week I picked up bikes for the whole family, my wife and i trade between towing a 3rd wheel and a trailer. I'm riding a Trek 7.3 FX, I noticed the tires compress a fair bit with just my weight, but with the 3rd wheel hooked up it seems to be a bit too much. Am I right about these tires not being suited for my weight?

My current tires are the stock Bontrager Race Lite Hardcase, 700x32c; 60 tpi. I'm wanting to do some limestone trails, and the distances I commute are pretty short, so the road slicks are not something I need, unless they're fine for limestone trails, which I couldn't find anything about their suitability for those types of conditions.

I'm not wanting the best of the best, and weight isn't much of an issue since I'm bringing plenty myself, but durability and puncture resistance are things I'd like.

Thanks in advance for the help.

Are you pumping the tires up before everyride? What kind of air preasure are you running?

IMO, you will be more comfortable with a slightly larger tire.
Look Continental City Ride in 37-622, they are a wider than the stock tire; yet a little skinny for
their marked size. I have a set on my Trek 520, run them around 60 psi. I would usually suggest regular
Schwalbe Marathon tires, especially for limestone trails; however I needed a set of tires earlier in
the spring; could not wait for e-commerce to deliver the schwalbes; a LBS had the city rides; been
fairly satisfied with them, plus they were fairly inexpensive.

Those tires should be fine. It would help if you had them properly inflated, however. They should be at 110.

I ride those same tires on my 7.5fx. Here's the bike, the tires, my loaded trailer, and me on tour back in June.

Thanks for the replies, I'll call around to see if any LBS's have either of them in stock martia. Just before I road the tires had ~108 rear, ~106 front, I'll get it closer to 110. Hist, when ya say they'll be fine, was that for the light gravel trails and my weight, or just the weight?

You should be fine on the weight with those tires. I started on my 7.3 when I was 250 and had no problems at all once I cranked the pressure up to 110. As for light gravel trails I am currently running about 1/2 mile a day (trail construction project) on gravel with no problems at all. I don't know that I'd want to be running 10 miles of gravel however.

Ditto on pressure. If you find spokes are getting knocked out very often, you could upgrade to a 36 count. But at your weight that shouldn't be a problem unless you're riding hard.

In the photo, I'm at 275, riding on the gravel and dirt C & O Canal Towpath, and hauling 35 pounds in the trailer. Aside from the fact I was riding with a fractured rib, I had no trouble.
