This may be a stupid question...

What are some possible adverse effects of running a different set on tires on the front compared to the rear.

Say for instance, 215/45-16 re010's designed for the NSX which have terrific turn in and Goodyear Eagle GS-D3 205/45/16 in the rear.

I would think problems with vibrations and tracking straight would be possible issues.


I am not doing this but just curious.

Thanks!

 

In the bestmotoring videos are sometimes ITRs with extreme different tire sizes.
Once i saw an ITR with something like 225 at the front and only 185 at the rear! Looks scary to me, but the japanees guy loved it!

 

the suspension set up plays a large part with the tire sizing as well

 

The "JDM" tire sizing is for increasing oversteer I believe, and is also matched to their weird shock/spring settings. Aamir, while I haven't driven either of those tires, if the Goodyears have less available traction (not as sticky) than the RE010s, you'd be asking for a bit more oversteer I think. Depending on how you want the car to behave, you may want to swap those front and rear (some instructor suggested that to me awhile back when two of my Azenis' were worn way more than the other two; that is, have the poorer performing tires in the front). Again though, it is all how you'd like it to drive.

 

i always wondered the same thing.....cool

 

Well I guess its not so much the different sizes. I know that many tuners DO run different sizes in the front and rear.

But DO they run different brand tires with different tread patterns. I have not seen any examples of this.

If tires are balanced at each corner, are there any problem that can arise from having different brand tire at both ends. That is my questions I guess.

more ideas?

i don't think it's a function of brand, but most people are more familiar with a specific brand they like, so they always stagger that brand.. not various ones.. racers stagger tire sizes all the time..

i've also heard that staggering tires for street use is not recommended on our cars, but I have nothing to verify that or back it up..

Damn straight you don't.

-Dave, who car runs fine with 1 20", 1 18", 1 17" and one 13" wheel with diff overall diameters and tire widths. It just crabs a little when driving straight.

 

I was not considering the different tires in order to stagger wider sizes in the front as opposed to rear.

I have heard from a few people that the NSX specific re010 front tires have terrific turn-in due to the way the front tires were designed by Bridgestone. As you may know the rear NSX tires are a different width and diameter. Thus I cannot run a full set of 215/45-16 re010's. That size was specifically made only for the front right and front left of the NSX. I dont think it would be a good idea to put these tires designed for the front on the rear of the R.

I am not all that satisfied with the turn-in at any tire pressure with my Goodyear's so I was wondering what bad effects I might encounter with running the re010's in the front and the Goodyears in the back.

Looks like I will just have to try and find out!

Hey, they be good eatz!

NSX specific RE010's wear very badly on anything other than NSX's. Just something to keep in mind. They were specifically designed for that car and have be known to wear out in 4-5k miles on other cars....

i don't think that's the kind he meant.. ahem..

Aamir, why not just get a full set of something else? trying to save a little loot?

Yah basically, I have the Goodyears and they are still brand new. Their turn-in is just really bad. I actually switched back to stock wheels and re010's because I wasn't enjoying the car. It was a NIGHT and DAY different going from the Goodyears to re010's. Much better turn in and confidence, car just feels much more sure footed. I felt nervous driving around curvy roads with the new goodyears.

I was thinking I might be able to alleviate some of the issues with the Goodyears turn-in by buying just two tires proven to have terrific turn-in and putting them on the front.

THen again, I am sure the Goodyears on the rear also contribute to the poor performance so just changing the front is probably not going to fully alleviate my problem.

 

On an R and totally depending on what type of driving you plan to do and at what limit you plan to drive it to I most likely wouldn't if I really didn't have to.

The difference in compound or adhesion or rollover of the sidewall would not be something I'd want to discover in any type of emergency situation on the street not to even think of the track.

Not to mention that the 215/45's are a rolling diameter of 23.6" and make 854 revolutions per mile while the 205/45's RD is 23.3 and make 867 revolutions per mile.

But in a standard passenger car like my Nissan Altima, of course I've run different tires/compounds (not different sizes) but only because I needed only 2 tires and the one's I used to have were discontinued, and the car is a beater AND I'm never ever gonna push it at all. But, that's just imho.

The advised way is not to do what you asked about but your car isn't gonna mysteriously explode if you did regardless.

Best of luck.

 

I have actually run two different sets of tires on the front and rear on the track (of course not by choice, if you've read my "blown tire" story).

Anyhow, because of the incident the day before the track day, I ended up throwing two JDM 16" with RE010 215/45/16 rubber on just so I wouldn't miss out on the action. Plus who wants to miss the first track day of the season?

And I have to say that it worked out very well for me (IMO) and the RE010 turn-in was very benificial according to my seat-of-my-pants track test (no times to compare or anything... )

To back this up, I ended up heading to a different (albeit bigger) track two weeks later, after replacing my two original front tires (yoko paradas) with a matching set and was rather disappointed with the results compared to having the RE's up front. Overall, it seemed much less predictable than the RE's and the habits I had formed with RE's weren't working well this time around, my confidence on the turns decreased (tho with some getting used to I did eventually get some better runs going).

But I suppose to qualify all this, I have to say that the RE's were *well* within their optimal wear giving great results, where as my almost brand new yoko paradas probably didn't stand a chance due to this fact alone. I guess that's what I get for bringing fresh tires to the track.

You could probably argue that I should have shaved the yokos a bit before going to the track like that... but my wallet and conscience would not allow it... In fact, I wish I could get a deal on a set of RE010's, as two of the four are now down to the cords... But I hardly think Acura will cut me any slack even if I tell them my sad story...

In summary, like most others have said, running different tires will change the characteristics of your car, it's just a matter of whether you like it or not... In fact, maybe after I work in the paradas a bit more, I'll run the RE's in the front again to see how they feel in a more fair comparison... but somehow I have a feeling that I will like having mismatched RE's up front again..

 

Are you referring to Parada Spec 2s? If so, I'm sorry for your poor choice. That's more of an appearance tire than a performance tire. For your sake, go and do lots of burnouts or something to wear them down so you can buy something else.

 

I have advan neovas AD07's on the front and goodyear Revspecs on the rear (both same size) both are excellent tyres and i have never noticed any adverse effects with them. I honestly cant see what difference it will make so long as both are good spec tyres with the same wear and speed rating. Maybe for track it might make a difference but for everyday driving i'd say it makes none!

Paradas are horrible tires compared to re010's

That's exactly it.

Most tire experts will tell you not to mix different tires front vs rear, because they will make the handling unpredictable. And that is very true. For example, let's say you have front tires that handle dry pavement better than the rear, and rear tires that handle wet pavement better than the front. All you need to do is to drive from a section of dry pavement to wet pavement, and all of the sudden the car might switch from mild understeer to severe oversteer.

Just not a good idea, if you can avoid it...
