I just rebuilt/upgraded one of these Tourist I picked up for free. The only really crappy parts were the bottom bracket, cranks and wheelset (at your weight these shouldn't be a big problem). You probably shouldn't put a ton of money into this bike but it is definitely better than most big box store offerings. That said, the reason I grabbed this bike is because it has a bunch of tire clearance. I think you could easily fit 40mm tires with fenders or even 42mm without. This bike is pretty stiff, but if you only weigh 130 and put on some 35mm tires on it (at an appropriate psi), it would be a very smooth ride. 35mm will absolutely fit on the stock rims with no problems. Larger decent quality tires will not make you noticeably slower on rough roads like you describe. Hope this helps!
