Hi i have a vmax 1200 trike with Sierra rear end with low profile tyres (came with these fitted) are low profile tyres a good idea i don't like them if not what is a good alternative tyre

As yours is a bike conversion, the speedo is on the front, so there should be no issues with changing the relative size of the rear rims/tyres.
Saying that, to maintain the stance, if you increase the depth of the tyre you should reduce the size of the rim.

At the end of the day, running low pressures on the back will give a less harsh ride, so you just need to balance that with the relative depth of rubber.

Maybe you just want more rubber than rim?

Yes I feel every stone on the road i thought it the depth of the tyre would help .

As big a side wall as you can get, and run at low pressure, a world of difference. The Dunlop GT qualifiers I have on the rear, look the same when they have 32 psi as they do with all the air let out, I run at 22psi.


I love the 'No Lean' rear suspension design on Big Blue. It has a big coil spring in the centre, with a shock running through the middle of it, and a height adjustable progressive shock on each side. It is a US import, and was still set to riding on the right, first time I rode it, felt like I was going to fall off, . Spirit level across the handlebars 12" from the kerb, lowered the R and raised the L until it was level

Just needs to tidy up his hair.

unfortunately had to put low profile rear tyres back on rear due to clearance issues think I will change rear wheels from 17" to 1 5" next winter just enjoy as it is for this spring/ summer

Or move your mudguards if you can.

Just because my comb is bigger than yours..



vmax, have you had a play with the pressure, you would be surprised how low you can take the pressure

thanks everyone for the advice on wobbly bits messed about with tyre pressures put a new Avon front tyre on its about 95% perfect
