Looking for slicks

Looking for slicks to fit on my stock 16" rims for a 99 Trans Am. I believe they are 16x8 correct me if I am wrong. I bought 17's but want some slicks for the track. I believe 10.5x16 will fit but not sure about rubbing. Let me know the best option.

You won't have any problems with a 26x10.5-16. M/T only makes the ET Street in that size, not the ET Drag slicks. Hoosier doesn't make slicks or the QTP DOT's in that size.

Thanks.
