Tyre size 315/25 R 22 and ride quality

It depends on the road conditions of your area.

I used to live in Northeastern which would cost me 1-3 tires a year on 25-30 profile tires.

Right now I’m in a much nicer weather area with smooth road surface. 25 has not given me any problem. My Lusso is on the Novitec spec. It rides great.

 

If you end up with these sizes, make sure go with PZ4. Stay away from Nero and GT.

 

I had in my f12 335/25-22 continental tyres. In my opinion they were better to drive, than normal size Pirelli p zeros.

 

I tried 21’s from my F12 on the Lusso before 22’s. 21/22 is the way to go on Lusso unless the roads are pretty bad.

I didn’t get the tune but I have full exhaust which use oem valve system. I don’t think the car is tuned for power delivery anyways, it’s not gonna have the feel of F12 and 812 in terms of acceleration so I passed on that. It would make sense to get if you are also getting the exhaust so the check engine light would go away. Still, you need to think about the warranty issue with your local dealer.

 

Just to get the details correct. The rears on the Lusso is 295, not 285.

A few things is worth noting.

If you switch to Pirelli PZero, you will see quite a step back in all areas.

Your car currently comes with MPS4S, which is by far the superior tyre, even compared to the new PZ4.

The 315/25r22 will not only ride harsher as it's a very low profile, it will also be quite a bit more noisy, and have a fair bit less traction in both dry and wet conditions.

If you like the look, do it for that reason. But be aware that it will come with a noticable penalty in noise comfort, ride comfort as well as driving performance.

Add to all of this the fact that your wheel diameter will increase which has the same effect as giving the car a longer gearing, i.e less accelleration and punch. If your Lusso comes with the forged wheels, my guess is that the Vossen wheels will be somewhat heavier as well - the tyres will for sure. Added wheel weight is also something that can be felt performance wise.

Just some thoughts.

 

You're most welcome. Happy to share

Whether or not a Novi ECU mod will make up for the wheels, I couldn't tell you. One thing is 90 hp, but my experience from the drag strip means that I'm much more interested in torque curves than hp numbers when it comes to the effect you can feel. If those 90 hp is only there in the last 500 rpm, you will only get anything out of them when you're flogging the car like was it a naughty mistress.

That being said, I have driven an Italia with a Novi ECU tune, and that was nice. Was it more powerful? Hard to say, but what it did do was this. It felt more alive and responsive, but also with a throttle that was easier to modulate - think Italia sensitive throttle vs. Speciale throttle. The ECU tune might not have given the car a lot more usable power, but it was better and more fun to drive.
Chances are the Novi ECU will have a similar effect on a Lusso, i.e refine and sharpen it up a bit. Will the power gain offset the wheels? I'm leaning towards no. It's a big and heavy car that already has a lot of power. Unless that torque increase covers a significant portion of the torque curve, 90 hp on top of what's already there is not a huge deal in the grand scheme of things. But do I think it's worth a try? Yes. I think Novi seems to have their program together when it comes to ECU tuning.

 

Hi Mike

Missed the fact that your Lusso is a T. In this case I would say that the ECU tune will definitely be felt. I haven't driven a turbo Ferrari with a Novi box, but generally ECU mods on turbo cars yield a noticable difference in power.

It did strike me as a bit odd if an ECU tune would add 90 hp to an N/A V12

Still, it's a big and heavy car with a ton of torque from the factory, so don't expect too much

 

You're welcome.

That's a good size and you can run a much better tyre.

IMPORTANT! It's not the Michelin Pilot Sport 4 you want, it's the Pilot sport 4S.

You could also use a 265/30R21 front and 325/30R21 or 275/30R21 and 325/30R21 tyre combo with the Michelin Pilot Sport 4S setup.
Ask Lamborrai what offset he has on the fronts if you want to run a slightly wider tyre all around. He runs 275 section tyres up front.

Good luck

 

Sawadee Mike,

May I be a party pooper and curb your enthusiasm for a moment?

First up - you are getting a great car. Even with no options, there won’t be too many Lusso in Bangkok so it will still be something special to see and drive.

I am not suggesting you don’t modify or tune the car, but why not take delivery of the car in stock condition, get to know it, get to love it, and then decide what you want to do about tuning. You will have a much better baseline of experience from which to judge what you really want. You will also get to learn the ride quality on 20” rims on Thai roads. Once you have a feel for that, you will be the best judge of whether 21” or 22” upgrade wheels are right for you.

For the Novitec tune, I am speculating that it will unleash more torque. Ferrari has left a lot of torque on the table with the V8 T because they want it to feel like a normally aspirated engine with torque building as rpm builds. They could have tuned it to have max torque from 1200rpm but then it would be like any other fat German super saloon. In my opinion, the increase in torque will make it less special to drive and you won’t get to redline the car as often.

A friend of mine has a Lusso T and an F12 among his stable. He thinks the balance that Ferrari has struck with the power, torque, ride and handling of the Lusso is just perfect.

Live with it stock. You can always get stuck into making changes later.
