About the 185/70R15 size
The front half of the classic 911 staggered set: 185/70VR15 front with 215/60VR15 rear on 6J and 7J Fuchs wheels, which is the SC and early Carrera 3.2 specification, and never rotate them front to rear. It is also the size most TR6 owners fit in place of the original 165R15 because it fills the arch better on a 15x5.5 rim and the sidewall is more modern. The Porsche N-specification tires that were sold in this size are long gone, so you are choosing between period-look classic radials in H and V and a handful of cheap T-rated options; on a 911 do not buy the T-rated one. No whitewall, no bias version worth having.
What the numbers on the sidewall mean
A 185/70R15 tire is 185 millimeters wide, its sidewall is 70 percent of that (about 5.1 inches tall), and it mounts on a 15-inch wheel. That works out to an overall diameter of roughly 25.2 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded.
In this size our picks are marked 89W on the Pirelli P6000 (1,279 lb per tire, rated to 168 mph). The first number is the load index, the letter the speed rating; a tire with equal or higher values than your placard is fine, a lower one is not.
Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.

Frequently asked questions
How much do 185/70R15 tires cost?
Expect $449–$449 per tire for a budget brand, $449–$449 for a mid-range tire like the Vredestein Sprint Classic, and $449–$449 for a premium tire like the Pirelli P6000. A set of four therefore starts at about $1,796. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 185/70R15 tires?
185/70R15 is original equipment on Porsche 911 SC (1978-1983, front), Porsche 911 Carrera 3.2 (1984-1989, 15 in front) and Triumph TR6 (1969-1976, 15x5.5 modern fit), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 185/70R15 tire?
For most drivers our mid-range pick, the Vredestein Sprint Classic, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Pirelli P6000 is worth the extra. On a tight budget the Nankang CX-668 is a sound choice.
Can I replace just one or two 185/70R15 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
