Ok so, I added a 2 1/2 inch level and am running stock 20" wheel with 33x12.50 Toyo Open Country M/T.. The only rubbing I get is a slight amount with wheels at full lock left or right.. I need some advice.. If I run spacers what size do I need and is there any one else already running them that could tell me a good brand and where to buy... The other question is, are wheel spacers safe, or would I need to buy new wheels and if so how much off set on my wheels would I need to correct the problem?
