Tire Questions

Currently got Dunlop WinterMaxx in 245/40/18. (Original size for 2009 is: 245/45/18)

1. Is it better to have 19" instead of 18? Would 19 fit?
2. Is 40, 45 or 50 best?
3. Buy summer or all season?
4. Best choice of those albeit economical in price?

1. 19's will fit but if you already have 18" winters there's no point
2. Personal preference. Thicker the side wall = better ride
3. Personal preference . If you want performance oriented then get summer tires
4. Keep your winters & get some nice summer tires…

Every tire is different.

I've done a lot of research on 19" tires & for the money the Hankook V12 Evo seems like what I'm going with.

What I was looking for was:

Performance/road noise/price.

They are a Max Performance Summer tire so I'll have the grip. Read some reviews & the side walls aren't the stiffest but road noise is pretty much non existent, they're good in the rain & I can get them for about $140 CDN/tire.


It'll handle better with wider tires (not bigger, 18" vs 19") & to be honest the stock RL suspension is your weakest point. Grab some Aspec springs if anything but get ready for a less comfy ride.


Oh and don't waste your money on 19" winters

1) Wheel size does not affect tire size. If it does, you sized your tires improperly. The only difference you may experience with a larger wheel is a more rigid ride, but you can always adjust PSI to counteract.
2) What does "best" mean to you? You want the tires to be the same diameter as stock or your speedometer, odometer, MPG meter will be off. Wider tires can give you more grip on the road, but heavier unsprung weight will slow you down. You want skinnier tires in the snow so you can push through to the road.
3) All season tires are appropriately named. They are designed to be used in climate which doesn't necessitate a dedicated winter tire. If you have winter tires, you should buy summer tires in my opinion. Otherwise you are leaving performance on the table.

Could you elaborate on this pls. Can i put 19" tires on the current wheels?

If so same measurements 245/45/19 or is 50 better.

Basically I'm wondering what's best combo for this model's stock measurements. Are you saying i'm better off sticking with 245/45/18, and make my future winter tires 45 as well?

Some shop on kijiji having a clearance sale. Kijiji snipes FTW


You can't put 19" tires on 18" rims… You'd have to buy new 19" wheels

The tire diameter equals the wheel diameter plus 2 sidewall heights. If you increase your wheel radius, you need to reduce your tire sidewall height by the same amount. Play around on this site to see what I mean: Tire Size Calculator - Tire & Wheel Plus Sizing

FYI, tires are sized by width (in mm)/sidewall height (as a percentage of width)/inner diameter.

The "best" combo depends on what you need. Winter and summer needs are different. In winter, you want less width. In summer you generally want more width without adding excessive weight. Regardless of your ideal target, you need to adjust the sidewall height to maintain constant outter diameter.

Pirelli Cinturato P7 245/40 R18 93Y driven 20kms on a new audi then they changed the mags for 20" and selling the tires.

Price 800CAD or 600USD.

Good tires? good size? good deal?

That's an awful deal for used. Tire Rack has them brand new for $160/tire. If it was $500 with tax, installation, and warranty, I would say, yes, but the first 10k miles are the best period for a tire. You will only get noisier and less grip after that.

Going to Tire Rack, using the Pirelli size above, and choosing summer tires less than $200, I think the Michellin Pilot Sport or Super Sport, Contenintal DW, Pirelli P7, or Bridgestone Potenza are the best bets. I haven't heard of any of the ones you listed being used on an RL here.

Should I choose 100W, V, Y or H? And what indicator tells me they'd be better on fuel consumption?

Continental DWS I've seen get choppy wear and are hard to balance as you put miles on them. I don't know about the DW. Michelin PSS FTW if you want to go summer and winter tires

TireRack may have good prices for the US market, but just across to Canada it becomes literally horrible.

Read about speed ratings here: Tire Speed Rating: What You Need to Know | Bridgestone Tires

If you don't plan on breaking 100 mph, any of those would be fine. There is no indicatir for rolling resistance, the MPG factor. One thing about low rolling resistance tires is that they increase breaking distance because they don't stop as easily.

I got winters man. Those dunlops are proving quite impressive.

Those michelins are an overkill. not spending more than 851$. Canadians.

I've spent some time comparing. This Tires Online Canada at discount prices : Winter tires, car tires, SUV tires of all brands beats TireRack on all fronts.

I only use Tire Rack as a reference, not as the gospel. I buy everything through Discount Tire. The tires will be the same regardless of vendor.

Yes, .

I got my PSS thru Discount Tire at 960$ with the warranty and install in 18". The bill was 1119 but that's without the 160$ total visa gift card discount they were offering at President's Day. God bless American pricing!

Have you considered crossing to the US for tires? I know a few people who have done that...

I got the Pilot Super Sports in 245 45 18. I haven't personally taken them in full blown heavy rain but they are well rated for that.

The ratings for the cinturado AS+ seem quite good. and from costco with all the pluses, 1k CAD all in installed. good deal no

Edit: 300 bucks more for super sports. hmmmm

The idea that an all season performs better in rain is a fallacy. It rains during summer. Usually a lot in a lot of places. Summer tires are required to perform in rain. However, they are not required to perform in cold.

I wish I would have realized that and bought summers for the RL before I lost it. You can run them year around in the South.

I am not sure i can even tell the difference between AS and summer tires. Plus this is a Grand Touring All Season, not just A/S.

Big difference

P7's ratings are same or higher than the SSP. Unless you tell me I'll get a better MPG with them, I'm not forking 300 more

I can tell you the drive on the PSS is better than the P7. Hamds down. But if price is the biggest factor, then p7 it is.

The link in my previous post is wrong.

Here's the link I intended: PirelliCinturato P7 All Season Plus

projektvrtex did you try both?

Check out tirerack ratings:

PSS




Cinturato





I'm willing to be convinced though just dunno how

You are missing taking a u-turn at 55. The only way you can get a direct comparison is to take both tires and run them on the same car, same track, same day, with the same driver. Then you would need to look at stoping distance and dry skid pad specs. If the P7 is an A/S, you will likely never find that since tire suppliers only test tires within the same performance categories.

In general, summer tires will have better dry traction, stopping distance, and cornering response. In order to achieve that, you sacrifice tread wear, road noise, and ride quality.

If Pirelli made an A/S that can hang with the Super Sports, then I would be blown away and give massive props to them. But until we see that direct comparison, I'm sticking with the Super Sports being the top of the line performance tire.

From the reviews on forums and ratings on tire websites, Tech_CL;s Hankook Ventus do rank up there with Michelin's Super Sport. And half it's price.

With such close calls in reviews and ratings, I think it becomes a personal choice in - as you say - what one is willing to sacrifice for what they want.

I know I will not worry about cornering at 120km/h or the slight difference in stopping distance and dry traction. they'd be not worth the noise difference alone, albeit the SS are not that noisy from what I read, but the P7 is much quieter from what i read in ppl's reviews. You add to it ride quality and tread wear, both higher on priority list for me than the ultra performance former characteristics.

I can understand why some with Aspec features, suspensions, lowering the car etc would like that. The RL's engine sure can do it. But generally the RL isn't a sports car and mine isn't Aspec.

the guy at costco asked with confidence: what's your car? 'Acura'. Which one? 'RL'. Ok so you need ride comfort and low noise; and he highlighted 4 options on the price list.

He made sense.

Yes, no doubt. Go back to post 5, my first reply, and see 2). "Best" is completely subjective. What is best to a 44 year old may not be what is best to a 24 year old. You own a luxury cruiser and if road noise and comfort are paramount, it is 100% understood. Only you can define what's best.

Buy what you think you will enjoy the most, even if that is an extra $400 in your pocket.

What i'm saying 007spy is that for the marginal if at all difference in ratings on performance, I'll take the quieter one that'll also last longer.

What I think is a fallacy is many minds is one is called summer, the other all season. While the categories tires are being tested and rated on, are the same, as per the above two tables. i don't care if it's called 'fun time' tire or 'romantic getaway' tire.

For this car we all share, with these two above tables, the choice between the two tires is relative to each surely, but regardless of age range. That only applies, if the younger ones are more susceptible to marketing gimmiks, not real & beneficial results.

Something to keep in mind, user rating vs industry ratings. Butt dyno isn't the same as industry tests.

I get what you are saying. What I am saying is that the scale's metric is likely not the same. If you had raw specs, I'm willing to bet you could see the difference. The performance category isn't just a gimmick. That said, I don't doubt you can find good or great tires for much cheaper.

True. I suppose I'm taking the approach where proof lies in the pudding. Ultimately if I average 600 people's opinion on their experience with the same tire, it gives a good general idea. And I suppose i'm not a big fan of the frenchies, but you seem to miss them

Yea. And it's not Minerva. The saved dollars become the cherry.
