What is the difference between ultra high performance and grand touring tires?

I have a 2005 honda accord coupe ex 4cyl. I understand my car is not a racing car and I don't plan on using it.

I'm looking for a set of all season tires. I'm currently living in michigan and would like tires that have the least hydroplaning in snow/rain, but at the same time would like to use them year round. I'm trying to decide between Pirelli Cinturato P7 plus or the Dunlop Signature HP

Added (1). On tirerack.com they have different options for all season tires. There's ultra high performance all season and then grand touring all season. The websites doesn't do the greatest job in differentiating the different types. If anyone can explain the difference between these two types that would be awesome! I don't care about price, but I also don't want to buy separate snow tires.

Is it ok to use red coolant in my 1996 honda accord lx 4 cylinder, 2.2l?

Flushed out my coolant system and i don't know if i should use green or red coolant. Does it even matter? I looked in the reservoir and it looked red but i don't know. I just got this car so i don't know what coolant is right for it, my dad already went and bought red coolant for it though… Was just curious if red would work for it.

What's wrong with my transmission?

Ok so I have a 2002 Honda Accord EX V6 and this morning I started noticing something wrong with my transmission because the D4 was flashing. Normally when I drive from a complete stop it shifts normally and shifts twice to get to about 42 mph. But today it shifted from 1st gear at a high RPM and when I tried to get it to shift into second gear it wouldn't shift to second. And normally when I'm driving at 55 mph and I put my car in cruise control the RPM stats at about 1600-1800RPM. But when I did it today it stayed at 3,000 RPM. I have an automatic transmission. Can anybody tell me what's wrong?

Door swap on 1997 Honda Accord - EX to LX?

Door swap on 1997 Honda Accord - EX to LX? - 1

Added (1). I have an LX and am wondering if the front driver side door from an EX will bolt directly on. Or are there differences between the two?

Car fan won't turn on unless AC is on?

I have a 1997 Honda Accord and lately it has been overheating. The fan in the car will not come on unless I run the AC but yesterday I was driving on a cool day with the AC on and it still started to over heat so I pulled over and let it cool down. After that, the check engine light came on.
Please let me know if you know of anything that might be causing this so I can get it fixed. Thank you.
P. S. I have already tried replacing the thermostat and it didn't fix it.
