if i were you, id get p265/75/15. im going to guess you have 15 inch rims. For brand it all depends. If you want badass all terrians, wild country xtx are sweet, but they don't last as long. I have a set of Open Country AT's and they are awesome, and last longer. Also you can go with P metric which is just standard load, but if you want a stiffer tire with beefier tread, go with LT's. LTs are more expensive but are worth it. that tire size i gave you is 31's, but just in metric form. For some reason they tend to be cheaper than 31/10.5s. I don't know why but thats the facts. I worked at les schwab for an amount of time
