Tyre sizes for a heavy bloke? What do you recommend?

Da Mighty Chicken

Hi peeps,

Just nearing the end of my build and at the moment I have some Panaracers Fire XC Pro 2.1s on Mavic XM719s, but after seeing the 2.3 conti gravitys on my wifes bike they look a little small. I really like the tyres just concerned I'm too heavy for the 2.1s?

So do you guys reckon that I'd be better off with some larger tyres, will these help spread the weight over a greater area or will the 2.1s be ok, maybe pumped up a little harder?

(bike is a P7 HT, my weight is approx 19st)

If you do recommend a larger tyre please feel free to tell me what tyre you had in mind, I'll mostly be doing XC, trail centre type stuff

seing as you already have these tyres, why don't you try them out and see for your self?

Yeah I can, just cant try them out without a bike, so was hoping that if the general forumites thought it'd be a better idea to go larger then I could sort the tyres out whilst I wait for my forks to arrive!

Ah - fair do's I think you'll be fine - I've rode on 1.8's before when I was 16st and it was fine for general XC/trail stuff.

you are not too heavy for 2.1s just up the pressures a bit.

Thanks Nick, what kinda PSI would I be looking at, 40-50? Max rim can take is 50 at 2.1 IIRC?

Nah, got royally messed about by a bike shop when trying to order my forks, I should have had this finished about 2 weeks ago! I'm now waiting on TFTuned to get the forks in from Fishers so I'm currently looking at end of next week for bike to be finished!

Thanks Nick, I get what you are saying, I may just hold fire for a bit then?

But is it normal to take a pump with you when you read the FAQs?

just try out differnet pressures. no tyre width is too narrow for your weight. think of all the roadies.anyway i usually run about 40psi for xc and about 30/35psi for dh,am ,fr etc. and even lower for when it's really wet. my friend rode at 15psi when it was really wet and muddy

yes I do.

105kg and use tyres from 1.9 to 2.6 depending on the bike. Road bike not included.

i think it just depends what you feel comfortable with, personally at just over 17 stone i didn't feel confident on smaller tyres so i now run with a 2.5 maxxis high roller on the front and a 2.35 on the rear and it suits me fine....
