TrebamGume - Your tyre tool;
TrebamGume is a vehicle-to-tyre compatibility finder and live catalog built by Proceptio. A customer picks make, model, year and engine; sees every factory and alternative size within ±3% rolling diameter, with load index, speed index and pressure; then gets matched to in-stock tyres that genuinely fit. Live in production for Gumiimpex, built for any tyre retailer or distributor.
245/45 R18The problem TrebamGume solves
Buying tyres online is a guessing game. A shopper knows their car but not its tyre size; they know a size on the sidewall but not which alternatives are legal; and even when they find a size, nothing tells them whether that specific tyre carries the load and speed rating their car actually needs. So they call the shop, or they order the wrong thing and send it back.
TrebamGume closes that gap. It starts from the vehicle, make, model, year and engine, then it ends all the way to a bundle of tyres in stock, priced and even compatible to fit. Every step is covered by real fitment data and warehouse stock, so what the tool says is compatible, it most probably is.
How TrebamGume works
There are three steps that every customer should meet. Firstly, identify the vehicle, secondly, see every size that fits, and last but not least, match a tyre from the stocks that meet the manufacturer's specification.
Pick the exact vehicle
Make, then model, then year, then engine - each step narrows to the next, so the customer never has to know a tyre size to begin. The catalog covers a deep range of makes and models, and resolving down to the engine matters: two cars in the same model year can ship different factory tyres. By the end of four taps, TrebamGume knows precisely which fitment data applies.
Every compatible size, factory and alternative
TrebamGume shows the factory fitment first, then every alternative size that stays within ±3% of the original rolling diameter - the band that keeps the speedometer honest and the car legal. Each size carries its load index, speed index and recommended pressure, so the customer can size up to a sportier wheel or down for winter without guessing whether it is safe.

For each compatible size, TrebamGume lists the tyres in stock and checks every one against the load and speed rating the car requires - a green badge appears only when the tyre meets or beats both. Each result shows the EU label (fuel, wet grip and noise), XL / run-flat / season flags, live price and availability. Stock and pricing aggregate across all warehouses, so the best real deal floats to the top.
More than a finder
The vehicle flow is the headline, but TrebamGume is a full tyre storefront under it.
Dimension catalog & combine search
Browse by width, aspect ratio, rim and season, or paste several sizes at once (205/55R16 + 225/45R17) to shop a whole set in one search.
Compare up to three
Put three tyres side by side across price, season, EU label, load and speed index, specials and stock, with the best value highlighted per row.
EU tyre label data
Fuel efficiency, wet grip and noise on every SKU, plus rolling resistance and best-use tags - the same data the EU label requires, made shoppable.
Seasonal & how-to guides
Winter-tyre law dates, a tyre-terms glossary, a fuel-savings calculator and dimension explainers - content that earns search traffic and answers questions before they reach the shop.
Four languages
Croatian, English, German and Spanish, with localized URLs throughout - built for a market that sells across borders.
Live multi-warehouse stock
Availability and pricing sync from every warehouse and aggregate to one view, so customers only ever see tyres that can actually ship.

Frequently asked questions
What is TrebamGume?
TrebamGume (Croatian for "I need tyres") is a vehicle-to-tyre compatibility finder and live tyre catalog built and operated by Proceptio for Gumiimpex. A customer picks make, model, year and engine, sees every factory and alternative tyre size that fits, and is matched to in-stock tyres that meet the manufacturer's load and speed requirements. It is live at trebamgume.hr.
How does the tyre compatibility check work?
For each vehicle TrebamGume holds the factory tyre dimensions plus alternative sizes that stay within ±3% of the original rolling diameter. Each in-stock tyre is then checked against the load index and speed index the vehicle requires, and shown with a green "compatible" badge only when it meets or exceeds both.
What can a customer do besides search by vehicle?
They can browse the full catalog by dimension (width, aspect ratio, rim, season), combine several sizes in one search, compare up to three tyres side by side, read seasonal and how-to guides, and switch between Croatian, English, German and Spanish. Stock and pricing aggregate live across all warehouses to surface the best available deal.
Who builds and supports TrebamGume?
TrebamGume is built and operated by Proceptio on the Microsoft stack (ASP.NET Core, Blazor, Azure, SQL Server). The same team that builds it supports it directly, and it runs in production for Gumiimpex.
