MGB Tires - customer feedback

Subject: MGB Tyres

Having run on the new PIRELLIs for a while now, I can echo what other people have said.

The ride has been transformed, cornering is much more controlled and it is one of the best improvements I have ever made. Well, not really an improvement as such; I had CINTURATO™s on the car back in 1983 but I had forgotten how good they were!!

Subject: WOW

I'm genuinely astonished how those CINTURATO™s have transformed the feel and handling of the B!

Dear Longstone,

I bought a set of PIRELLI CINTURATO ™ tires from you for use on my 1968 MGB roadster and thought you might be interested in the following feedback;

I replaced my 9 year old Yokohama 175 70R 14 tires with genuine PIRELLI CINTURATO ™ 165 H14 tyres. This has dramatically changed the gearing:

175 70R 14 have a 23.5" diameter off the car. At 24 psi the height from floor to centre hub is 10.875" = 68.339" rolling circumference (3.142 x diameter).

165 HR14 have a 24.5" diameter off the car. At 24 psi the height from floor to centre hub is 11.75" = 73.837" rolling circumference (note the disparity between off the car diameters and actual rolling diameter - perhaps in part because the Yokohama tires were under inflated at the MGB recommended 24 psi? I note that other users of 'modern tires' use higher PSI and so the difference in rolling diameter may be less for most persons).

73.837" - 68.339" = 5.498" (this is the increase in rolling diameter) 5.498 / 68.339 x 100 = 8.05% (this is the percentage increase in rolling diameter and thus represents the % change in gearing.

So: The effect of changing the tires is that I now have a 3rd gear which works beautifully for the lanes. The gearing used to frustrate me as 3rd was just a means of getting from 2nd to top and then I used overdrive. 3rd and 4th seem to have regained their meaning! I have yet to try this out on the motorway (in theory 3000 rpm should now reduce to 2760 for the same road speed) and to evaluate any changes to fuel consumption. I have noted the discussions re modern tire pressures and will experiment with such - probably 28F / 30R. Note that this will increase the rolling diameter a little more again. In addition the tires looks great and receive approving comment from those who recognise them. They are also physically larger and look more in keeping / scale etc with the car - my opinion but there you go! I've highlighted the tire markings in white (grout pen) which is true to period and will see how this looks / lasts.

Just thought you might be interested?

Best, Simon
