Another Eibach Question SORRY

[altimacruiser]

I was wanting to know if the stock tires would be okay to leave on the car if I installed the Eibach springs, wheels and tires are out of the question for right now but the springs are within budget. I had a few concerns I wanted to check out before I bought them and then regreted it. Also has anyone bottomed out with these springs yet? I only ask because the road conditions in New Mexico arent the best and potholes and road splitting is a problem here also speed bumps and inclines are pretty prevalant in the area so I dont want to scrape the car anywhere so if anyone can help me out I would appreciate it. Thanx.
