Koblenz Rim/Tire Sizes

[BadNBlackCobraR]

My size options are as follows

front:
18X9 with an "ET" of 35 (i think its some sort of backspacing)
or 18X 9 with ET of 45

Rear:
19X10.5 with an ET of 10
or 19X10.5 with an ET of 30

What backspacing is best (i know one of those 19X10.5 sizes are MADE for mustangs) and also what size tire would be best, i was guessing like a 245-45-18 for the fronts and maybe 285-35-19 in back? help is appreciated.

If i could help you I would look into a different rim...I was at a wheel place and was about to order these rims...price tag: $3500 for wheels, tires, mounting, and balancing.... When I asked why he said that the rims are not made in the correct offset for a Mustang and are "custom-made". And the only size that you can get would be 19's they said the 18's aren't made.
