Tyre advice please

[hankhill]

I bought a Raleigh Motus this summer, for leisure cycling on tow paths, etc. Now that winter is here and the paths are muddy, it’s sliding all over the place on the standard CST Zeppelin road tyres. The tyres are 700x40c on 622x19C rims. What are the largest/ widest/ chunkiest tyres that I could fit on these rims? I realise I should probably have bought a mountain bike not a tourer like the Motus, but it was too good a deal to miss. Any guidance will be most welcome.

low Enough noise levels for road use, plenty of grip and reasonably low resistance

You may just have to be wary of the clearance on mudguards, fork bridge etc - just check before buying as the Zeppelins have quite rounded profile and no knobblies

Thanks, they look ideal. I will check the clearance as the mudguards are pretty snug, and the rear one carries wiring for the built in lights.

The rims on one of our bikes are 700 x 19 front and 700 x 21 rear which were both originally fitted with 700 x 45c tyres, only okay for tarmac.
I've fitted continental cross king 29 x 2.2 which has improved the grip in the way you wish.
I had to fit wider mudguards and make sure there was enough frame clearance taking into consideration that the tyres are not only wider but taller as well.
tyre sizes and rim fittings are a bit of a minefield and took me a lot of research to get right, this chart may be helpful

Different brands of tyre even of the same size inflate differently but I could let you know the inflated width and height on the 19mm rim if you wish

I use Schwalbe Land Cruiser's on a full suspension converted emtb as I ride on both road and tracks, they are good enough off road and great on road and come in a range widths.

I'd like to go a bit wider than 40 if I can get away with it, partly in the hope of a softer ride. Dave, can I take you upon your offer to measure yours? That would be much appreciated.

The tyres on the 19 rim measure 54mm high from the outer edge of the rim and 55 mm wide across the tyre at the level of the outer tread "knobles" when inflated to 34psi.

Thaks for the info Dave, I ran a tape measure and I think that would be pushing my luck. I don't really want to have to re-engineer the mudguards as it's a pretty much brand new bike. I'm gonna go with the Smart Sam 700x40c. Thanks all!
