I've not been cycling for 20 years and just got my old bike back off my parents that they have had hanging up in the garage. Still looks in excellent condition but need some advice on the tyres.

They are pumped up as hard as they can go (and feel rock solid) but when I sit on the bike they don't half flatten out!

Now, I'm a tall lad, 6'4" but only 14st 4lbs, so not really a big fatty.

Question is, can you buy different tyres that support the bigger person and won't flatten so much?

Cheers
Richard.

It depends on the cross section size of the tyres for the amount of pressure they can take. However 20 year old rubber will have perished so I would recommend new tyres and inner tubes anyway

My 28c tyres will go to 110psi, the 23c ones on the road bike will go to 120psi. When I put the bigger 32c tyres on the commuter these will 'only' go to 80psi max

To get these kind of pressures you WILL need a track pump.

I'm topping 15 stone btw and have no problem with the tyres flattening out

i use a 2.1" schwalbe road tyre on my mountain bike when commuting to work each morning and run them at 65 psi and they don't flatten out and i'm 16 stone

What sort of bike is it, what sort of tyres are they and what riding will you doing?

I'd also advise new tyres after 20 years

take it from me (5 kids) - rubber perishes!!

Agree with Kieran.

My roadbike with 23c tyres gets 120 psi too. I'm 6'2" and 13st 10lb (not quite as lardy as Kieran) - no prob's with squishy tyres!

And yes, get some new tyres - should be £30 for the two or so.

Fantastic - thanks guys

Yes,completely agree with changing the tyres.

I'll take a photo of the bike tomorrow - it's a bit naff with the grip twisting gear changes (left handle for three cogs at the peddles and right handle for 6 cogs on the rear wheel) - not the quickest at changing around but I'm sure I'd get used to it.

I'm only looking to use the bike to get fit - makes more sense than sitting on a exercise bike in the house watching TV - so not looking for a racer or mountain bike.

Cheers

I would stick some new tyres on after twenty years, not for safety, but for puncture resistance and reliability.

I am 16 plus stones, did 25 miles on mine today at speeds upto 35 mph downhill, 25 mm tyres at 120 psi rear, 100 front, you should be fine !
