MG MGB Technical - 15in tire size

Just ordered 15in Minilite look-a-like wheels to go on my 1972 MGB (squeal of excitement). The question is, i see that the safe recommended tyre size is 185/60 15. But there are so few choices. I'm looking at 185/65 15. Will these rub, oh and i might lower it later.
Thanks in advance,

Hello,

According to that calculator you have the right size.

I have that size on my B-Gt without any problem. But it depends of Minilite's offset to fit well or not.

Cheers,

You can fit in up to 195 x 65 - 15 (subs for the MGC tire) but as far as matching the OEM MGB diameter, I think you have it pegged with the 185 x 60

I'm using 195 by 60 michelin XM-1's on my 15 by 6 Performance minlite replica's. Standard guards, no rubbing.
The tyres are good in both wet and dry conditions, are a low rolling resistance, quiet, and have a high treadwear rating.

According to the calculator site 195/60x15" is the good one.

But if you have a non-OD car, I suggest 195/65x15 as it gives 3% increse of diameter.

I've been using P195/60R15 tires on my MGB for years. 60 series tires also offer a much wider range of choices than the old 65 series tires. They're also the right size to keep the speedometer reasonably accurate. If rubbing inside the wheelwell is a problem during hard cornering, install a Panhard rod. The improvement in handling will be obvious.

I've been running 195x15x55 tires. They are about 5% undersized and lower the car about 1/4 inch. (diameter is 1/2" less) The alloy rims are 6" wide rims. The car handles like it is locked to the ground compared to stock. In my experience, You will find the rear axle shifting and your tires rubbing in back in aggressive driving.(front = no problem) The panhard bar will tighten up the rear end handling issues and will stop the rubbing.

I have ran 195/60's on Minilites for years myself. I agree with Barry, the rears will rub in aggressive driving without the panhard. I'd think 65's might be taller than you'd need.

I run 195/60R15 on 15" x 5.5" x 72-spoke wires wheels. I have no rubbing, even in aggressive driving. Bushings are Superflex, all else is stock.

I am running the 185 & 195/65/15 tires. (4 mgs on line this week} Softer ride, than the 60 series tire. (the fun of getting older, soft ride in a M.G.}

185/70 R14 - Standard wheels in Summer (French Roads)
V Rated 195/55 R15 - 6" SAABS in Winter - rub on inner right a little (but not so you'd worry)

I agree with your description of "a little" rubbing with the 195/55/15 tires. My 67 has stock fenders and only occasionly will there be a rub, when the car is being pushed to the limit on a rough road. New nylon bushings and fiberglass mono leaf springs.
