If you are worried about the temperature rating the best thing you can do is keep the tire pressure up to the proper temp as under inflated tires build up heat faster and according to the owners manuals I've read and the studies that have been done, higher inflation is better for traction when at risk of hydroplaning as well.

OK, it might be time for my lecture on UTQG Temperature ratings.
First, is that the term "Temperature Rating" is a misnomer. Fundamentally it is a speed rating - and has a relatively minor affect on rolling resistance. However, vehicles where fuel economy is a primary design feature also do not have high speed capabilities, so you will usually find that LRR tires have S and T speed ratings.
Just be aware of the fact that rolling resistance, traction (especially wet traction), and treadwear are tradeoffs when it comes to tread compounds. Don't expect extremely high wear or traction with a LRR tire.
