question about choosing tires.

im going to change my tires, and the tire shop suggest me not to waste my front tires, also my wallet is kinda tight right now, i dont know if im going to drag race my car and front tires and rear tires are not same will cause any issue? if i use 245/35ZR19 front, and 275/35ZR19, is that a good setup? my oem front tires are Pirelli P Zero 245/35ZR19, rear tires are 265/35ZR19. i want to change my rears to michelin pss 275/35ZR19. i thought wider tires will give more grip? or im totally wrong? or i should change front and rear for the drag and DD? anyone pro can tell me how should i make this decision?

Too many unknowns here to give a definitive answer. You're not sure if you're drag racing or not. If you are replacing just the two rears, get 2 more P-Zeros for regular driving.

245/35R19 F 275/35R19 R is OK. Probably a little more understeer, but the extra width may help a bit from a standing start.

Switching to drag-specific tires for the track will help your 60' times, but will put more stress on the driveline because they can withstand a more aggressive launch without breaking loose. I have not gotten a lot of input from M3 guys drag racing regularly, so not totally sure if there are any known weak points to be concerned about.

Usually just a standard traffic ticket and you will incur 1 point on your record. Its not advisable IMO

It can make your handling feel strange, unstable, or unbalanced. Putting PSS rear with Pirelli fronts will promote understeer, which makes the car less fun to drive fast. A matching set of tires will almost always handle better than a mixed set, even if one of the tires in the mix is superior.
