I'm sure I'm posting in the wrong place since there are mostly hardcore riders here, but I thought I'd give it a try anyway. I bought a mid-priced Mongoose Mtn Bike about 8 years ago, and almost immediately ended-up moving for a new job somewhere which was not bike friendly and didn't even put 10 miles on it.
Here I am many years later wanting to start riding again, and I hate to admit it, but I've gained quite a bit of weight since then. It obviously still has the stock tires on it, but now when I sit on it, I seem to weigh way too much for the tire (I'm 6'1" and around 250.. my weight is the reason I want to start riding again ). Given that it's an older bike it has 26 x 1.5 tires on it. I don't know what PSI the tires are inflated to, but they seem to be a good pressure and it's still not able to hold my weight. Is there a tire/tube combo you'd recommend (maybe my OEM tires and tubes are old/weak)? Am I just too heavy to be on a bike? Would upgrading to a bike with 2" wide tires be enough if there is no hope for me on the 1.5" (the bike is inexpensive enough that it doesn't make sense to upgrade to wider wheels and tires.. doubt they would fit anyway)?
As far as rides, I plan on doing mostly casual stuff on paved bike trails, with the occasional off-roading on gravel trails and what not, but nothing too serious (if this is of any help for a tire suggestion).
