Hi more noob tyre/puncture advice pls


New Member
Hi i posted this part of request for advice in the welcome Mat area however realised it may be more appropriate here.. so here goes :smile:

I purchased a GT Zum S2 and am very pleased with the bike. I decided to go with a hybrid type due to the route being mostly road and on a national cycle network canal footpath however it is really quite rocky in places. I expected the bike to cope, which it seems to be doing.

The problem lies with my rear tyre having sustained 3 punctures in the last 3 outings. They have all been slow punctures and have coaxed them home stopping to pump every now and then.

So help please...

The bike has Alex ASD - 1 rims and Kenda K West 1.50 tyres. Is it that the rear tyre is not suitable with the relatively sharp rocks? Do i need a wider/thicker tyre (and inner) MTB style? I've tried running a lower psi in the rear hoping it would help but to no avail. Ran recommended pressure and still no joy and puncture happened again. Are presta valved inners more susceptible to punctures for some reason?

If i should change the the tyres what do you recommend to fit the rims i have?

Thanks for your help guys :thumbsup:

P.s My Girlfriend has also been cycling this route on her Carrera Subway and it has coped admirably and no punctures.

Whilst she is about 4.5 stone lighter than me, I am not THAT mahoosive at 13.5 stone..(could this be an issue?)


When you get a puncture Zumzum, it's important to try and locate the cause - if it's a thorn then it could still be in the tyre or it could be something sharp on the rim.

Are the punctures in the same spot on the tube?


I would maybe think about changing your tyres, Kenda's in my opinion are not the best, try something by Continental, Specialised or Schwalbe.
