A few Q's

[4_cell_racer]

I just obtained a B4, and was told B3 wheels don't fit I've tried the B3 wheels I have and noticed that they seem to make the B4 wider . I know the max width is 250mm for any Regionals and Nationals, so I'm asking the Q for club meets (for now!!)

B4 with B4 wheels
Rear (arms level) = around 245mm
front (arms level) = around 245mm

B4 with B3 wheels
Rear (arms level) = around 260mm
Front (arms level) = around 254mm

Now My Q's are

Will the handleing of my B4 be made worst useing the B3 wheels (until I get some more B4 wheels)

Will any other make of wheel fit the B4 axles (front and rear)?

Also with regards to tires/inserts.......what sort will I require for the tracks in the Mid West section of the regionals (Oswestry, Kidderminster, Stoke, Coventry)? Wet n Dry selections please

Any other help gratefully received

Cheers
