stratton said:Just patching up my sons bike after he trashed it again, fitted a spare tyre to replace the bald
front. The rear tyre is a 2.00 and the front is now 2.1. this I don't suppose will cause any
problems but it did set me thinking, what would be the effect of putting say a 1.5 on the front
and a 1.75/1.9 on the rear? Would the bike handle the same but be slightly more comfortable? My
bike is a rigid and I am at the age where comfort is a serious consideration.
There's no reason why front and rear tyres have to be matched as general handling is not affected
by different widths* - each tyre doesn't "know" what the other one is. But tyres should be
appropriate for the rims. Most modern MTB rims can take quite a wide range, so at least 1.5 to 2.1
will probably fit ok.
The wider the tyre, generally, the more comfort you'll get. Narrower versions of the same tyres will
be be less, not more, comfortable! A wider front tyre will absorb buzz and shock better. However, a
slick "road" 1.5 tyre may provide more comfort on the road than a knobbly off-road 2.1.
* Except a narrower front tyre may provide a slightly better steering "feel" (less squidging and
steering may feel more precise). Traction will be reduced, though.
