Another benefit of 205/50-15 F (or 225/45-15 R) is that there's enough sidewall to protect the wheel from potholes. My cars are regular drivers and anything more aggressive might cause issues here in Michigan.

 

Everybody loves those Konig Rewinds…..I personally think they are ugly but to each its own…..I love the factory wheel look…. Plus there are plenty of other companies that make wheels on 4x110…..

 

Rota has a selection of 15" x 7" rims with the 4 x 100 bolt pattern.

Best handling: some quality 185/70R13s. Keep the swaybars and the stock positive front camber. You can play the car like a musical instrument, controls are direct, light, and responsive.

Best grip... I have some 255/35-13 A7s on 13x10 magnesium wheels...

Handling and grip are two separate concepts and in some respects are at direct odds with each other. High grip can make for evil handling, with heavy control inputs, dartiness, tramlining, all sorts of unpleasantness until you are up at the coffin corner of lateral G.

 

The odometer is the only thing to really be accurate, the speedometer can be as much as 10% high and still be in spec.
same for the tach, it can be -.5% to +10%.

 

Yep, the tires need to match the car. Really old cars fitted with modern wide radials could reach the limits of the chassis before the tires, which will make for unpredictable handling.

The '85 FSM shows the error range of the speedometer.

 

Excellent comments from peejay regarding handling, tires and the odometer.

When I managed a Speedometer shop in KC, we used odometer readings to determine error. Our advice was to drive the car on the high way past 5-10 mile markers and note the percentage difference in mileage registered and mileage driven. What ever that number was determined the correction that was needed. While we didn't service allot of Asian speedometers what we did test were fairly accurate. The worst were GM mechanical speedometers as they typically had 5-10% error after 10-20 years.

Regarding tire selection, it is helpful to think in terms of a "package." The package would consist of the tires/wheels and the suspension parts uses to manage the tires. Case in point, back in the 80's GMC released the Syclone pickup truck (4.3lL turbo with full time AWD) and somebody brought a new one to an autox I was at. On the OE Goodyear Gatorbacks the Syclone truck put the Corvettes it was classed with on notice. Before the next event the owner fitted a set of BFG autox tires. The truck was slower. The sticky tires twisted the trucks chassis like a pretzel and caused unloaded tires to come off the pavement. The GM engineers got the package right.
