I have no experience with low profile tires so I have no idea how they ride. I know a lower sidewall will be stiffer, but I was hoping that with newer tire technologies, they may have improved from what I have read. So the question is this. Can anyone clue me in on how a 45 or 40 series tire might ride? I know there are many other variables involved (tire compound/tread/width/etc.) but I'm looking for more of a general idea. I definitely want to limit the road noise for the long highway cruises and worry about how the lower profile tires will handle road imperfections. I have found 40 and 45 series tires in 16" and 17" and that will give me plenty of wheel options to compliment the car. I could also use 15" tires and comfortable go to a 60 series tire, but it will limit my options on wheels. I don't want to molest the body so I am limited to a maximum 25" tire and that may even be to tight. I would like at least a 225 width for those occasional (cough cough) times I "might" want to get on the go faster pedal. it will only see 3 seasons (no snow ever) so probably a touring tire of some sort.
Car is a 1976 Triumph TR7 that will have a GM L33 V8 truck engine. I'm not building this to be a great eco car, but definitely a highway cruiser that I can still open some eyes with from the in-town stoplights. Roughly 325+ rwhp when all is said and done. Probably a 60%-70% highway car.
Any advice?

I am no tire expert. I remember the TR7: "The Shape." Great project!
Personally, I would be against really low profile tires, unles the rims are carefully matched to the look of "the shape." I think low profiles are more prone to blowouts and rim damage in potholes, especially if you run lower tire pressures to soften the ride a little.
You burried the lede! The thread title should be Pick low profile tires for my '76 TR7... that'll get lots of clicks.
