Click the "Comparison" tab on the left. Then you can put in the stock size and compare it to whatever you are thinking about getting. This way you can see how the overall circiumference will affect your speedo.

Other than that you just search around to see what size tires people have managed to fit, how much fender rolling was required, and if they used spacers or not....

205/55R16 is the standard suggested size. When it comes to looks, I also think this looks the best with almost horisontal side walls.

205/50/16 keeps the standard circumference almost perfectly.

205/55/16 is 2.9% larger than stock, which means a reduction in gearing, and a 2 mph error on the speedo at 70.


I know it's not much, but these things add up. You wouldn't want to +T your car just to throw away 2.9% of that new found torque by making the wrong choice in tire size.

205-55-16 is the 'summer' size.

Fits/works like factory, used to be common enough as the optional size on WRX, Impreza, Accord, Camry Passat etc 'sportier' models, same with 2/7/9 Volvo up to ~15 years ago or as the base model on Matrix/Vibe on steelies now .

The 50s drive all darty/don't protect the rim/no advantage. Wider & they're all flubbery & don't break-away predictably & are more prone to rub or hydroplane.

2.9%. From what? 185-70-14 or 195-60-15 ski-dan tire size?
Isn't that within brand & rolling radius variation w/different pressure in different temps (unless you've got nitrogen/don't have leaky tires or top-up or adjust with air?).

205 55 16 would be my choice.

biggest issue is does the tire compound you want come in that size?

He doesn’t even know what RS4s are. A high mileage Michelin tire would be right up his alley.
