Road noise in fr-s - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Can I get away from road noise in my frs if I change from a low profile tire (215/45/17) to a (205/50/17) touring tire?

Number9 · 12-10-2016, 02:17 PM

Should I switch to a touring tire instead of a low profile tire?

You're confusing tire design with tire size. You can have low profile touring tires.

You would be better served to buy a tire that gives you the handling performance you're looking for and then putting sound deadening inside the car. These are noisy cars with very little sound deadening. Any tire will have road noise, some worse than others. You can't get away from it, only minimize how much of it gets inside the cabin.

Taller profile could improve comfort but road noise associated with tires is pretty much a function of tread pattern. The two attributes are relatively independent. It's probably true, though, that "touring" tires tend to be quieter. Tire Rack can provide info on which tires are noisier. Their chat function puts you in touch with people who can help.

As the previous post suggests, you may want to consider whether the noise you are objecting too is related to tires at all.

Stock tires are LRR. So, you are not really going to get quieter. Low rolling resistance tires are the most efficient. Which is why toyota puts them on the prius.

Add sound deadening mat, turn up the stereo, or get some studded tires. Then take them off, it will sound quiet in comparison. Just saying that it is fairly quiet stock. The car is 88db. My s2000 was 96db stock...

Low rolling resistance tires are extremely noisy!!! It is easy to spend 80 a tire and get more grip and very quiet. The lrr tires are like using plastic wheels.

This is a sports car, not a GT car. The sound deadening material is minimal. In fact I like to hear the small rocks or even rain hitting the wheel arc area.

Correct. I blocked off the intake noise generator which helps. With the Supercharger this juvenile device is discarded entirely. Now pushing in the clutch to coast at 70 mph literally makes no difference to the sound level.

These cars have very little sound deadening from the factory. Noisiest car this side of a Cayman in which the stock engine noise level can actually reach pain threshold!

Exactly. On my very first test drive I got maybe 100 yards down the road and was hooked.

I'm old enough to know that Subaru has deliberately and successfully tried to recapture the pure mechanical excitement of driving. The big difference from the old days? Complete anvil like reliability compared to those old sportscars.

I owned an Alfa Romeo GTV6, 2.5 l V6 putting out a then impressive 150 hp. This BRZ is the spiritual successor to cars like that. The BRZ would run circles around any of those old cars. And never break down while doing so.

Trying to avoid roadnoise in a sportscar is like trying to avoid calories at McDonalds.

You don't.

If you want quiet, get a touring tire in the stock size. It will be quieter, at the expense of performance elsewhere.
