ET34 on the front may cause problems re: protrude beyond the arch by around 8 mm - I stand to be corrected.

Ignore this response - I assumed the fronts were 8.5 inch width

Should be fine if fronts are 8 inch width - rears will have plenty of room.

Fronts are 18x8J and rears are 18x8.5J

Fronts are 18x8J and rears are 18x8.5J

Double check clearance front and back though when wheels are on re: safety first!
