They fit my car well.

I did have to hammer, that all depends on what your BS is. If your trying to fit a tire that size on something with stock back spacing it will be hard to do. But with 7.5" BS mine actually fit on the car. Just barly touched the inner fender well. So I made a good 1.5" or so of room for safety.
And yes the 325MT is 28" not 30". And these things really dont grow anything like a slick. They are belted so the stay in place a lot better. I did not cut at all on the front or back and they dont rub. Only had to clearance the inner well. Not many folks can say that about a 28" tire this size. And it's due to them not growing at speeds.

I also put a set of the 325/50/15's this week and I had to do some hammering in the fender but they fit and don't stick out. I really like the 28" height and they hook better than my 26x10" ET drags that I had on my car for the last 6mos. I ran 10.30's@130mph on my very first outing with these tires on 150HP n2o in full street trim. Later Clint

Tim, you are using some wheel spacers right? Just want to make sure, that makes a difference.
I could kick my rearend back a bit but I could end needing a custom driveshaft.
Or I could cut and box that front spot by the lca's if it's snug around there.

Kevin, I am sure you could fit the 325 tire in there. There are plenty of guys riding around with the 335 nittos that have just rolled their fenders a bit. Man I can't wait to see the car in person, the dyno vid was sweet!

Right, but 1/4 spacer helps a bit. Every bit counts when fitting 28's in the wheelwell. I have 28x10.5 et drags on my car on 15x10/7.5 backspace pro stars, and from what i hear, i would have to do a bit more bfh'g to get stuff to fit.

ET's Did you use a spacer 9secpacecar? I would like to make mine fit with no spacer too but will have to do some more work to make them fit.
