Just in case your curious

Raphy posted photos of his 3 wheeler with 120/70/19s. They look like they should fit under the mudguards.

Blockley`s are 701dia. by 119 width.

Yes They fit under the mudguards

what brand are the 120/70's?

Michelin Commander II

thanks

I have just ordered another set of Excelsior Competition H 4.00 x 19 tyres. They are a huge improvement on the Avons, with very progressive grip and reduced bump steer. Being cross-ply three stud race tyres (designed for use on Bugatti Type 37 and the fronts of Type 35), they have nice stiff sidewalls, which transmit steering forces to the tread, far more accurately than the Avons do and they don't "tuck under". I also feel they are very balanced with either the Yokohama Blue Earth or the Michelin Cross Climate 175/55 x 15" on the back and you can do three wheel drifts with enough room. The only downside is the tyre life at around 4000km but that is two years use for me so not an issue. They were very expensive in France but Longstone have now opened a French branch, although I see on the tracking that my tyres have still been shipped from Doncaster last week.

I cannot recall if there has been an earlier discussion on this, but do you know how do those tyres compare with other Excelsiors, Blockleys etc for life and wet weather performance?

Recently had drive of Nigel Pitts Brooklands M3W fitted with a pair of Michelin Commander II 110/90 B 19 tyres and was most impressed. My M3W has Blockleys that I have always thought were considerably better that the original Avon SM's but these are another step. The steering is lighter, the cornering more confident and the braking greatly improved with no locking of wheels until you really lean on the brakes.

Both Nigel's car and mine are running with ATR adjustable shocks and I would say that these help with the ride greatly. The less flexible sidewalls of the Michelins transmit more road irregularities but the shocks can be softened a click or two to compensate and restore a comfortable ride, something that wouldn't be possible with the standard Spax.

As Nigel's car has only done a few miles with the new tyres we cannot say how they will wear. These tyres are normally used on Cruiser type bikes front wheels and all the reviews give them good marks for durability, they have a harder compound in the centre and softer on the edge to give a longer life and good cornering grip. The cost of the tyres is comparable to the Blockleys and Avons, sightly cheaper actually. They fit under the mudguards but don't fill them as much as the Blockleys, you can remove the wheels without taking the mudguards off though, so a better fit really. The speedo will be further out with something like 8% error as against 6% with the Blockleys. I would say these tyres are well worth considering if you don't mind that they don't have a "traditional" look.

Presumably you still use inner tubes with these?

They do have inner tubes.
