Subject: DB 3 ltr tyres
By now I have sorted out most little problems within 400 miles of test driving my DB 3 ltr (ignition, carburettors, fuel pipes, fuel filters, spark plug caps, main brake cylinder..). Now I started some test driving on the motorway (here I discovered a blocked fuel filter at the higher througput needed) and that the tyres have suffered from long rest (I should have lifted the car but always thougt it will be finished very soon so why bother..). I think I will buy 2 new front tyres. It has 6.00 x 16H Dunlop now. The best supplier for veteran car tyres in Germany seems oldtimer-reifen.com they have different 6.00 x 16, the only ones that would allow 160+km/h are Dunlop and Avon (both up to 210 km/h). But the Dunlop ones are only rated for max 475 kg load, which would be a bit low for this car. Any inputs on tyre selection for the DB Lagonda, especially the 3 ltr ?

Another point is tyre pressure: the manual specifies 25 lb/sqr in = 1.75 bar for the front and 30 lb/sqr in = 2.1 bar for the rear. I tried higher pressure especially for the front first and than lowered to the specified (hoping that the wobble from the stand still bump would be less) but with fast steering movement left/right the car swings up (feels to soft). What is your experience or recommendation for tyre pressure ?

P.S.
This morning I called oltimer-reifen.de, they recommended to change to 185R16 radials, but I see they have a bit smaller diameter and are a few mm wider which will not look nicer and smaller diameter brings up rpms on the motorway even more plus I do not know if radials turn the steering much harder.

Another recommendation from a friend this morning was Blockley tyres which he is using on his Feltham Aston, but when I look at the profile even the 5 block pattern looks a bit "rough" to me

Suggestions?

Yours,
Peter
