    Tire Sizes

    Tired Out Again!
    Mark Ibenthal. Overland Park KS.
    So you'd like to buy some new skins for your MGB but everyone laughs when you mention the tire size? Well you are not alone.... Until 1974 the MG Car Co. recommended 155 SR 14 as the standard size with 165 SR 14 as the `size-up' option. I recently researched the above mentioned problem for my oil spreader and was unsuccessful in locating the correct size, short of Coker Antique Tire and their prices are very modern! However in talking to the guys at my local Tire Rack they were able to come up with actual dimensions that make this all a lot less painful and much less expensive. Read on......
    A 155 SR 14 is 23.7 inches tall.
    A 165 SR 14 is 24.4 inches tall.(both acceptable standard sizes)
    A 175/70/14 is 23.78 inches tall! This is an O.E.size for Mercury Topaz and is in good supply. Tire Rack also indicated that the minimum wheel width for the above mentioned size is 41/2 inches.

    I've been running Firestone 185/70R14 on my '68 MGB.   That size fits with no rubbing anywhere even under hard cornering and looks very nice on the car.  They need replacement this spring and I'm having difficulty finding 185/70 for 14" wheels.   The search goes on.

    Found the best option with help from TireRack.com,  ConsumersReports and a few other sites that highly rated the Pirelli P4 . . .  and they come in 185/70R14.  Bought a date matched set of 4 and after restoring the Rostyle wheels they should be on the car in a few days
