My 69 XR7 currently has the stock brakes + tire/rims and my next project is brake conversion + rim/tire upgrade. Looking for 4 wheel brake conversion kit recommendations + the needful rim/tire sizes.


Did some research on wheel size com which suggested
225/50R17,​
225/45ZR18,​
235/45ZR18 can be used (depending on brake caliber rim clearance​
needs) without wheel/axle modification. Anyone used any of these configurations without clearance issues?​
I believe the above sizes would require either the 17x8 or 18x8 sized rims depending on the brake conversion kit clearance needs.


Hoping to do the 4 wheel brake conversion done the right time.
