Ive had BFGs on several cars, and I agree they arent great, but....they are fine for just cruising around with in good weather. They have the look you are looking for, and if they are the only tire you can find that fits I wouldnt hesitate.
If you do have 5.5" rims, a 245 tire is too wide. Thats almost 10 inches of tread fitting a 5.5" rim?! You must have something wider than that. Definitely confirm your rim width before purchasing, especially if you buy online.
