285/45/18

I have two 18x9.5 wheels and I just ordered some 285/45 rubbers for them, I'm stock height and was wondering if I'm going to have to roll my fenders if I drop it 1.25"

Those are BIG tires--28.1" diameter vs 25.7" for the stock 245/45-17s--740 revolutions per mile vs 810.

This will make the speedometer read slow by almost 10% (the car will be going 10% faster then the speedo says), and there will be a nearly 5% reduction in torque to the ground; also because of the larger diameter...

I can change it to read right at work, no worries

This was a 305-45-18 with a 1.5 drop in the rear. I had to roll them at this point but not with 285 when I had the roush wheels

This was a 285-40-18 on a 9' rim. I added 20mm spacers to flush it out
