Upgrading wheels for triathlon

Hello,

I plan to participate in my first triathlon this summer. This will be a 1/4 Ironman, which includes 45km of cycling. I have a Specialized tricross sport bike (2012) upgraded to 105 components. I haven't changed the wheels, so I use some entry-level cyclocross wheels (32 spokes front & rear, 700x32c tires).

I have been doing quite lot of commuting and touring, but I have never raced on a bike. My goal is to do the 45km in ca 1.5 hour. And finally, my question is: is it worth to buy some entry-level road wheels (like shimano wh-rs30 or mavic aksium), or at my level I won't notice any improvement compared to my current setup?
Or, maybe, should I just buy some narrower tires?

Pass on the wheels the ones you mention will yield little in speed. Wheels that are deep and designed to be aero will help but cost mucho!!

Yup.

Get some nice light smooth ones, and if you want to go nuts, spend an extra $10 on some light tubes.

Contental GP4000s, vittoria rubino pro, vredestein tricomp, shwalbe ultremo, etc are all very nice.

Thanks for all the replies. Just to get an idea: how much shoud I expect to benefit just from changing the tires? i.e. let's assume that at my best I can do the 45 km within 1h30min on my current set up. Will the difference due to changing tires be measured in minutes, or it'll rather be just couple of seconds on the whole distance?
