Trek DS 8.3 tire advice
Hi
I use the bike for a 12k daily commute and riding on the weekends with the kids on hard packed trails (secretly hoping they get into it more and we can do more adventurous off road biking), I looked at the 7.2/7.3 but wasn't confident the wheels and/or frame were up to the task, I'm 6'5'' and 200lbs.
Anyway love the bike, I'm not going for a speed record but I feel like the rolling resistance is a bit much the tires are the stock Bontrager LT2, 700x38c. The question I have is without getting slick road tires what would be a good option to maintain the stability but not the width, I was thinking about getting a 700x28 tire, I think that's the thinnest I can go safely on the current wheels. I assume I have to get a different inner tube as well?
Maybe it's just me I have the PSI at 80 which is around the max but I can visibly see the tire flatten when I get on, I'd like to be able to increase the PSI as well. I live in the Pacific North West so we get plenty of rain.
Finally question what is the difference between a 700x28 and a 700x28c ? what is the 'c' for.
Many thanks!

If you are thinking about hanging them anyway, have you tried pumping them up to 90 or 95 ? If not, why not?

There will be visible flex in the tire, but as long as you don't feel the rim hit the ground when you hit a bump then you are not under-inflated.
I ride 700X32 tires and keep them between 80 and 95 psi and I weigh 240 lbs, so your 38 mm tires at 80 psi should be fine.

I can't imagine going below 32-35 on a DS. Particularly if you are on any kind of trail. I would suggest a tire that is not as "knobby" as your LT2's. Something like a Bontrager H5 or the even less aggressive H2. Of course there are plenty of other examples in other brands such as the Marathon Mondial . Some of the other less "knobby" Marathon models are also popular among riders on this forum.

Does the inner tube have a rating for how much PSI it can handle? or does it all come down to the tire? Are different inner tube brands better at handling a higher PSI?
thank you again!

When it comes to pressure testing, most manufacturers go at least 50% over maximum recommended pressure... tht's just common practice!

Yes I see what you mean, I guess a 32 is also fine, can I just ask a follow up question, apologies I'm a completely noob at this stuff.

No matter the name on the inner tube odds are it came from a factory in Taiwan or China.
