Tires for my aksium wheelset

Just bought a set of aksium wheels and they came with mavic aksion tires. Does anyone have any experience with these aksion tires? I have a basically brand new set of vittoria rubino pro tires I could swap them with if you think I would be better off. Any suggestions would be great.

Since we are coming into the off-season, and you have them...use them.

Treat yourself to a pair of continental GP4000s tires for next season.

Weight and psi have a great effect on tires.
210-215 for me.

You are a GREAT candidate for 25mm width tires.

Run them at around 95 psi.

I like Michelin Pro Race (currently on "3"). But there's so many tires, and it certainly has nothing to do with the wheels they're on, so the fact they're Aksium's makes no difference. My normal advice would just be to run whichever ones you have that you prefer until they wear out, then use the others, but if I were your weight, I'd go out and buy something in a 25mm, and sell off the 23's - going for durability, light weight, handling, whatever your preferences and price range are. I ride 23s at 90-95 and 100-105, but I "only" weigh 165.

Throw those aksion tires in the trash immediately! Same with the Vittoria Rubinos. Throw them all away!

200 here and that's what I do. Although I also use 23mm tires and run them about the same or a tad higher.

What type of difference will a 25mm tire make? Will the bigger tire slow me down? Also can you explain to me how higher psi helps? I bike for speed, im training to start racing.

The wider tire will enable you to run a lower pressure without pinch flats. The lower pressure and wider tire could actually be faster than a narrow, high pressure tire. There is a myth about higher pressure and narrow always being faster (the myth that they always reduce rolling resistance). This is probably true only for extremely smooth surfaces, like tracks. On normal road surfaces, especially those on the rough side, lower pressure will be more comfortable for you and will also flex and roll over the road surface roughness rather than bump over them. The flexibility will be faster, and the comfort will give you more endurance and ultimately speed. The only possible downside is that the wider tire will have more frontal area and be less aero. The difference of 2mm, plus considering the overall wind resistence of the rest of your bike and your body makes me think this is irrelevant compared to the benefits.

There's a bunch of charts and formulas that can be used to correctly inflate a tire based on load weight (body (clothed) + bicycle weight). Same as motor vehicles - there's an optimum range for pressure based on desired load, handling, fuel economy and comfort. It's not always "highest is better".

Google "Tire Drop" and you will find an excellent article on how bicycle tire pressure.
