Tire 1 inch thickness difference, 2 inch overall diameter difference

**Tempter** · November 24th, 2011 02:47 PM

Hi Guys,

Just wanted to ask kung marami bang disadvantages pag ang pinalit na gulong ay 1 inch thicker than the previous? So lalabas na 2 inch difference sa overall diameter ng gulong.

TIA

Tire Size Calculator - tire & wheel plus sizing

Hi ulit,

Kung ganon, original plan kasi dapat hindi ganon kalaki, pero dahil sa recommendation nung manager which I trusted I went for the bigger tires at 8 ply ba tawag don? Newbie kasi ako. Then later saka ko nabasa na delikado pala pag pinalitan ng mas malaking gulong kala ko ok lang yun. At syempre tiwala din ako sa pinagbilhan ko kasi matagal na sila sa ganon at yun ang nirecommend nila sa klase ng auto ko.

Meron pa kaya akong habol dito? Ano kaya ang pede kong gawing aksyon at kung sa pede lumapit kung sakaling ideny ako ng pinagbilhan ko?

Thanks!

is it possible you misunderstood?
perhaps he was saying, you can increase your tire size to give you better vehicle control. but you have to manipulate your aspect ratio, such that the overall diameter does not significantly change. some people find the ride rougher, though.
increasing your tire size per se, will throw off your speedometer and odometer readings. also, the new tires might rub against your wheel well or chassis.
other than these, i don't think your safety will be compromised. in fact, increasing your ply rating to 8, brings it to the tougher light truck category.

For what car and what are the tire sizes involved? It depends also on that really. I tend to upsize my tires on some of our cars, and in some cars, the OEM size is really small.

Mga sirs,

Revo yung auto.

Ang tanong ko na lang is dapat ba akong magbase dun sa tire calculator? I mean does it really apply in real world scenario?

Bale yung nakakabit na gulong before is 205/65/15 at ang pinalit ay 195/80/15. In terms of handling, sayad factor no problem, concerned lang ako kasi sabi don sa warning ng tire calculator ay may possibility of brake failure. Mga 6% kasi ang difference. At napansin ko rin na nabawasan ang hatak which is I think normal, concerned lang ako dun sa brake/safety factor.

Thanks ulit for the replies. ;)

Unless you're carrying heavy loads, that tire is over sized indeed and not really needed with the Revo. That size and ply rating is most likely the tire for the Hiace Grandia. This may also affect your fuel consumption drastically.

I would have probably upsized to a 215/65R15 or 195/70R15 at the most with that set-up.

Tinry ko nga sa Tire Calculator ung 195/70/15 mukang mas ok nga yon. Kaso ang mali ko lang siguro hindi muna ko nagresearch ng husto before biting the bullet. Ang nasa isip ko kasi talga same size yung kukunin ko, kaso nagtiwala ako dun sa recommendation ng manager which looks like he knows what he's saying.

Mukang wala na ko magagawang iba but to swallow this, unless gagastos nanaman ako for a set of new tires, haaaaayyy...

Or meron pa nga ba kong ibang maggawa?
