if i remember correctly the offset is 35mm..
5x112 on the lug holes..and i havent heard of anybody going wider than 225/40'z on the tires
without rolling the fenders.
some say the 225'z will rub...but i have'em
on my '95 e320 w/no problems. good luck

ps-u might want 2 go 17'z if u want a more
comfortable ride...thats what i did.
