I am a large guy, nearly 2 metres (78 inches) tall and weigh about 160kg (350 pounds). I am aware that bikes are not really made with me in mind and that my best bet is to have new wheels custom built with 36 or 40 spokes etc but that is currently not affordable.
As it stands now my rims seem to be holding up however my current MTB tyres are 29x2.25 and can only take a maximum of 90kg or so they say and the back ones sidewall is splitting. I looked at the Schwalbe algrounder 29x2.35 and this is rated to carry up to 136kg per tyre and can be inflated up to 3.7 bar.
My question is really if I buy these tyres can I just slap them on? IE, go from a 2.25 to a 2.35 without changing rims or anything else? My current tyres are tubed knobbly MTB tyres. I use my bike to commute to and from work only every day so riding on road. Sometimes a little gravel through a park but that's rare. For what it's worth I have lost 20kg (44 pounds) already so the weight is coming off..... Slowly but surely.
