28″ tires rubbing on the front. What are my options

I got a really good deal on some 28" mud tires and rims. Only problem is that they rub on the firewall in turns. I tried setting the shock preloads all the way up, which helped a bit but was not enough. I have a few questions. Do you think a 2" lift kit would fix this? Can I run a different tread tire just on the front and leave the back the way it is? I really like these mud treads but I was thinking about getting 28"’s for the front that have a lower tread. Also, how much clearance from the firewall would I need to prevent rubbing when the shocks are compressed all the way? I attached some pics. I can’t really return these tires (part of the deal). I guess I can always order 4 tires for the rims. These tires are 28-10 on 14" rims. If I have to get new tires, can anyone suggest 28" tires for the 570 that won’t rub?
