2005 XFire Limited Coupe...bought used from local Chrysler dealer
and didn't realize iit had two (2) different brand tires on the oem rims as follows:
Front=Sunny...........................225/40ZR/18 92W XL...Height=25.1
Rear.=Goodyear Eagle RS*A...P245/40R/19 94V..........Height=26.7
Note: XFire has oem stance.

Time for a tire change, and leaning toward the Hankook Ventus V12 evo K110 all around
After reading the various choices for staggered sizes.... still a little confused which way to go.

Choices for Front with oem rims (18x7.5):
1. 225/40/18...Hgt=25.1....oem size.. .current tire heigh=25.1
2. 235/40/18...Hgt=25.4
3. 245/40/18...Hgt=25.7

Choices for Rear with oem rims (19x9.0):
1. 255/35/19...Hgt=26.0....oem size... current tire height=26.7
2. 275/35/19...Hgt=26.6....closest to the current tire height shown above
3. 285/35/19...Hgt=26.9
4. 285/30/19...Hgt=25.8....closest to oem height.

Looking for some suggestions which way to go front and rear.... including any effect on
1. Actual speed to speedometer reading
2. If actual odometer mileage might be affected with rear tire height...from oem to ?

Thanks in advance!
