The MT version of the tyre is 30" and the AT version of the tyre is 29.something. The AT's fit standard suspension with minimal rub and the MT rub really badly on the front. Just driving in the carpark at work caused then to rub in the guards and going down driveways above walking pace lead to the plastic clips on the inner guards being ripped out.
The springs are great, took a trip to Tuff Truck on the weekend and they ride really well. Initially it felt a little loose in the back, but once they settled they are fine. Took a speed hump at speed last night to compare the springs and shocks to standard, and the back definatly bounced less and felt much more stable. The car has been transformed. While you can;t go around corners as fast due to the higher centre of gravity, you feel safer at the lower speeds as the car site nicer. This is probably due to the rear shocks being almost twice the diameter as the originals.
Overall I am extremely happy with new tyres and suspension.
