Tyres....Radial, bias-ply or cross-ply?
#1
Here's that guy from Holland again and being the square peg in the round  hole that I am, here's another question.
My Rosengart will be delivered within a few days 
We renegotiated the deal when after three visits it was still hardly possible to testdrive it properly due to electrical glitches and a dying ignition. Eventually  it ran well in second and reverse (..sic..) but wouldn't really pull in first and third (me thinking it was an ignition issue). Steering and breaking were 'encouraging' (and a lot better than the Morris 8 two seater I drove last month)  notwithstanding bit of a bumpy 'n' shaky ride.
We managed to limp back to the verdor''s garage, complained, his mechanic came to show me how to drive properly (....) but by then no spark could be tempted to jump from the plugs any more (probably the coil was fried by jump-starting attempts two days earlier with a 12 volt starter battery......so we started twisting the vendor's arm as by then we were under the impression that more harm than good woud be done to the car by further attempts by the vendor and his team of mechanics ... So we bought it 'as is' and leave the cosmetic respray.. some people even say that being  brush-painted it has it's charms as well...

Anyway... the tyres - spare included - need replacing.. two old Firestones on the front, two Yokohama (...sic...) motorcycle tires on the rear axle and a crumbling spare  the rear deck... 

Now not being hindered by any knowledge or scruples I'm slitghly biased toward radial tyres (because of their presumed / assumed directional stability)  but non of my pre-war driving friends could tell me from their own experience (!!!) the. pro's and con's of either cross-ply or radials... They all just stuck to cross-plies (in some cases these extortionally Michelins...) and even not having driven  any of their prewar cars on radials they dismissed that idea at first. hand.

Now I'm considering Avon SM tyres  in 4.00x19 (as that's the size my rosengart should run on); they are radials according to Longstone (France) but I do not like buying in France as French suppliers take ages to ship and  they always use Collisimo.....expensive and still slow in delivery, track&trace stops working at Gare du Nord.....terrible .

Alternative might be the AvonAM7 Safety Mileage MKII's in 4.00x19  as they are available from another supplier at a better price, free shipping and delivery usually within 5 days....

Other alternatives: the Excelsior Comp and the Longstone, the tread pattern of the latter please me more plus the 'pedigree' of that tread pattern even though mine wil be no racing car.

So how. about your esteemed and much appreciated. opinion on this issue? I'm a newby in pre-war cars, so willing to learn..


BTW. I'm attaching a pic of the car... hope it'll appear.
