We're currently running Vredestein Sprint Classic 185/70 HR15 80H tyres on 5.5 inch wide 72 spoke wheels. They were provided by a shop that worked on ours and other Healeys and was also the Vredestein distributor. We've added trunnion bearings and camber/caster adjustable top plates which would presumably have an impact on handling as well as a slightly smaller Moto Lita wheel, which will impact effort. Ours is a 1962 Mk II, and we have not had any problems with clearance or rubbing. The distributor lists them for $ 240 Cdn. ($ 176 US; dunno if that would be recommended retail including install etc., or the price to pick them up at the door). We were at the Van Dusen All British Field Meet in Vancouver a week ago, and one of the owners was very enthusiastic about the Michelin XAS tyres, so I'll want to look at them.
I use Miata.net to calculate and compare tire sizes; anyone else got favourites?
I checked in at the local Canadian Tire store but they don't carry 'our' sizes. The young chap suggested 195/65 15 as a size that would match the circumference closely and that they have in stock; however, I'd want to look a tire calculator for widths as well as checking recommended wheel widths.
First, I gotta find and decipher the date of manufacture and determine how soon it's replacement time. Wear ratings aren't a major concern, as we tend to age out rather than wear out. And I don't have the skills nor knowledge to determine if Brand A is better riding or handling or braking than B. Darboard time! Later, Doug
