You're joking, right? It understeers with the stock tires at all 4 corners at the limit, going wider in the rear certainly isn't going to fix that.

This. Just because you can get a car to rotate doing something ham-fisted, doesn't mean it's set up for oversteer. I've done powerslides in LS400s before. Doesn't mean they need to understeer more.

Can't tell if serious, or troll.

I'm. But I'm pretty sure this is related to thread topic. Stock wise 86 don't have too much power so it's good as is. 😛 But if you add some more power to it lets say 50-100 extra hp, Won't a slight staggered setup be better?

*Thread topic is how to select proper tire size for "performance"?*

No, most of what we experience is under steady state cornering, adding power does not magically change the handling balance of a car, the front end will still wash out at 'X' mph in 'Z' turn whether you've got 50 horsepower or 500 horsepower. While adding grip to the rear will allow for more power sooner it will only exacerbate the already existing understeer balance, again assuming the rest of the car is left as-is.

A staggered setup would be a bandaid that does not address the underlying problem, as alluded to above by @jawn oversteer on a stock 86 is caused by ham-fistedness, deliberate driver inputs, or road conditions, usually a combination of all three.

SOme one check my logic here. Formula 1 cars are the fastest race cars in the world. Formula 1 cars have staggered wheel set up. Therefore staggered wheels set up bc racecar.

I really think our car should have some with a staggered setup like 215 front 235 rear. Instead of drift all you want 215 square.

When you have their power/weight ratio, you can too :)

I've read taht the tire/wheel size is all set by the regulations.

If the F1 designers had their way they would prefer larger fronts to optimize balance and run larger front brakes.

Don't be too simplistic, it's also weight distribution as well.

Last time I checked there is a motor sitting back there with those wider tires. Rear and mid engine setup is a whole different ball game.
