DIFFERENCE__BETWEEN__18´s,__20´s__OR__22´s

Hello folks!

I planed to run my 68 Impala, which is going to be with 540BBC twin turbo, on 20/22 inch torque thrusts.

Then, many people told me with that amount of power I will only have tire smoke with such tires due to the less side wall height.

I dont want to go with 15´s by all means and so I decided to keep the same tire outside diameter but to decrease the rim diameter by using 18´s (talk about the rear wheels).

Now I wonder if it makes a difference if I go with 20 or even 22 inch or with 18 and therefor more side wall height (would be one 1-3 inch more side wall, depends on the used tire).

If so I would go with M/T drag radials or maybe BF Goodrich´s DR, you can give me a recommendation on that.

Meanwhile I saw that they also offer 20" DR but how I said, I have been told the magic is in the side wall height.

In the members rides gallery I see almost only 20 and 22 inch wheels and I cannot imagine that none of that cars got a punchy engine, so what is your experience?

In your opinion, will I improve traction by going down to 18" and what about 20" DR?
