I am looking to create a fitment guide for our magnums. I need your guys help. Please list the tire size and rim size of combinations that will fit.
I.E. 275/45/20 on a 20" x 9" rim.
UPDATE:
Here is some info I have found.
The LX platform is designed to accommodate up to a 275mm width up front and a range offset from 12.5mm to 24mm. You want to stay between 28.6" and 29.3" in tire diameter, optimally. You can go as small as 28.3" in tire diameter to keep everything calibrated correctly on our cars, but no smaller.
Magnum Bolt/Lug pattern = 5X115
20"x9.5" - 12mm to 20mm offset
18" tire recommendations
255/55/18
20" tire recommendations
255/45/20
245/40/20 - smaller OD from stock and will leave a bigger gap
275/40/20 - comes close to fender, but shouldn't cause any clearance problems
22" tire recommendations
Front
255/30/22
265/30/22
265/35/22
Rear
255/30/22
295/30/22
265/30/22
265/35/22
Here is a good site with info and comparisons on tire sizes/offsett and backspacing - Wheel / tire size calculator / comparer - BIGCUSTOMWHEELS
Please double check with your tire shop. I don't want to be held responsible for you purchasing a set of wheels that don't fit. If see anything thing that needs corrected, please let me know.
