Ooops...tyre schoolboy error?

Iain C

Just upgraded the tyres on my 07 Fuel from 2.2 Bonty Jones XRs to 2.35 Jones ACXs and gone tubless at the same time. I'm really concerned about mud room, seems OK round the sides, but the sloping piece of tube that connects each side of the hi-lo chainstays is very close indeed to the middle of the tread of the tyre (the bit you roll on on a perfectly smooth surface if that makes sense).

How much mud room do I need here? I reckon I have 4-5mm. Is this going to be a nightmare, or will it be OK on all but the claggiest bridleways, and get better when the tyre wears a bit? I did have a big problem with the XRs getting totally clogged up in really sticky mud, but that may have been partly due to their inability to shed much.

Only one way to find out! The scraping effect in some cases can be quite useful if it sheds.

I knew you were going to say that!!

Best find me some mud then!

There might be mud at cannock today - we havent left yet you could always join us for the family trail....

p.s. have you got pics of your new tyres on so we can see the clearance pls?

Iain C

Not sure I'm up for the family trail mate...bit hardcore for me. Perhaps a run round the carpark might be OK? Anyway, been busy preparing the gorund and getting foundation materials for the "Bike Shed"...should be going up tomorrow!

Here's the pic...as I said...tight! (I was right in the pub, they are 2.35)

Yep thats tight alright....
Allthough I looked at mine over the weekend and my new tyres are nearly as tight at the arch on the seatstays!

Erm, see my second thread in workshop/tec.

Mud room might not be the problem...chain room might!
