Tires: new tires ,rims, crome rims, factory rims

Question
I have a 1998 Nissan Frontier 4x4. In the winter I had studs put on the factory rims, drove fine.
Just recently I bought crome rims and tires for summer. Tires are same size as studs. They are MasterCraft AT 235-75-15. Since putting on new rims and tires the truck pulls a little to the left and sometimes a little harder when applying brakes. Seems not to drive as smooth, almost like a tiny shimmy to it. Have any ideas on the problem? Thanks for helping I love this site.   Suzanne

Answer
suzanne,
It sounds like you may need to take them back and have the balance checked. There could also be some mud packed on the back side of the rims and it needs cleaning off. I'm not sure about this tire brand but it could be them. You could have a brake pad sticking and causing the car to pull when applying them.
