wider rear tires for RWDs

[badkuk]

isip ko kasi it would provide better grip/traction; and it won't affect steering in any way. me other issues kaya sa driving dynamics/stability?

based on what I know, thats the main reason, to provide better grip/traction because it has a larger contact patch, this is necessary for cars with powerful engines.

other issues? not as aerodynamic?

but it will increase gas consumption a lil'bit ryt?

Bigger tires at the back could affect handling. They might provide more grip and stability, but it doesn't mean things would be easier when managing a tight corner while going fast. Grippier back end than it was designed for would mean stress to your limited slip differentials and understeer.

Maybe, anyway most cars that need them already have big powerful engines that are not fuel efficient..... their rich owners wouldn't notice.

My 911 has 225/50/16 front and 245/40/16 rear.

My Corvette and Chevelle has 225/60/15 front and 295/50/15 rear.

The Camaro has 225/60/14 front and 275/60/14 rear.

The wider rear helps to grip the road at heavy footed launches, but with a 454, even the 295 squeels in 3rd gear!

I also helps to eliminate oversteer during high speed turn.

If the car isn't designed for wider meats (tires) in the rear, there may be fitment issues, and yes, it will increase understeer.

Primarily, this is to provide better traction for off the line acceleration for RWD vehicles. FWD vehicles have the added benefit of the engine's weight to provide additional traction in the first place.
